Introduction
Why do some people move towards goals, sometimes creating something out of nothing, and others are always “scarce,” “someone didn’t give them” or “diminished”? And how is it that certain negative thoughts can stay in our brains for years, poisoning not only our motivations but also our relationships? It seems as if some of the inner attitudes live inside us for years, literally preventing us from developing.
Imagine that your brain is a magnificent garden where ideas, plans, dreams blossom. However, there may be weeds in this garden – negative beliefs and resentments that, according to some studies, can exist in a passive form for a very long time. We are not talking about the banal “I am in a bad mood today,” but about deep programs that can remain active (or semi-active) in the brain for up to three years, and sometimes longer. All this time, they quietly undermine our confidence, our faith in ourselves, our ability to set and achieve goals.
To understand how these long-term toxic beliefs are formed, and most importantly, how to detect and “disarm” them, it’s worth looking at the question from the perspective of neuroscience, psychology, and social influence. In this article, we will discuss the specifics of such “poison in the brain”, how it affects life and what steps will help to get rid of this baggage, which sometimes undeservedly “tends” for years.
Main part
1. The phenomenon of long-lived negative programs
Have you noticed that sometimes even after a reconciliation or a change in circumstances, there are still shards of negativity in your head? For example, once the boss said an offensive phrase or a friend betrayed your expectations, and it would seem that life moves on, but inside you periodically pops up a bitter feeling – “and he (a) was wrong!”. If such emotions are retold (even mentally) as a mantra, a stable network of neural connections is formed responsible for the reproduction of this resentment.
According to some research in cognitive psychology, memories associated with strong emotional experiences can be sealed particularly deeply. Every time we recreate a situation and react emotionally to it, we feed these neural circuits. As a result, it becomes part of our belief system: “I am always treated like this,” “I am undervalued,” “I will never gain respect.”
Reasons why these “poisonous” thoughts last a long time:
- Lack of work. When we do not understand the conflict, do not seek a solution, emotions can be preserved in the subconscious.
- Constant self-deprecation. People prone to self-criticism often fuel negative scenarios, which enhances their “living” in the brain.
- Confirmation of surroundings. If there are people around who support complaints and negativity, it "flowers and smells." For example, friends who also like to blame everything further strengthen your confidence that the world is unfair to you.
In the end, this “poison” turns into a habit of thinking and seeing the world through the prism of resentment and lack of something. A person complains that something was “not given, not provided”, effectively absolving himself of responsibility for changes.

2. The mechanism of the “victim” and “author” of their lives
Why is it that some people do things themselves, while others do things differently? Psychologists sometimes use the model of “victim” and “author” (or “creator”) in the context of life scenarios.
- Victim. A person who tends to see the causes of their problems outside: “I was not given”, “Not offered”, “I was not appreciated”. Victims rely on outside help, not their own internal resources. She is passive, because she believes that little depends on her own actions.
- Author (creator). They seek opportunities and resources, not excuses. If something is “not given,” he asks, “What can I do myself?” “Where can I get what I need?” Instead of blaming the outside world, the author builds a plan of action using the available opportunities and knowledge.
Interestingly, the transition between these two positions (the victim and the author) is primarily a change of belief that happens in our heads. One might say that a “poisonous” program is a victim setting that says, “I don’t have the resources, I can’t make a difference,” or “Everyone is to blame.” The author’s attitude: “Yes, sometimes not everything is perfect, but how can I influence it?”
The difference is that the victim sees no reason to change, while the author perceives failures as challenges and seeks solutions. The presence in the brain of these long-term beliefs directly affects whether we will be satisfied with life or remain in endless complaints and claims.
3. Where does the poison that lives three years come from?
Some sources mention an approximate period of three years (or more), during which a negative attitude can actively affect our behavior if it is constantly fed. Why three?
- Repetition of experience. When a person returns to an old resentment or negative belief regularly, for example once every few days, this “program” is fixed. Essentially, it’s like training muscles – the more often you repeat, the stronger the muscle.
- Retrospective justification. We like to find confirmation of our beliefs. If you believe that “you are always deprived,” you will notice any situations where something went wrong in your favor, ignoring conflicting examples.
- Combining with other negative beliefs. One “poisonous seed” can attract similar ones: distrust of the world, confidence in their insignificance, anger at loved ones. All this merges into a general negative, from which it is difficult to get out.
It is important to realize that such toxic thoughts are not “once and for all” given. The brain remains neuroplastic, so we can “reset” and get rid of this “program” step by step. But first we need to recognize its presence and destructive influence.

4. How do you identify this toxic program?
Sometimes we don’t even realize that there is a similar “infection” inside us because we’re used to blaming circumstances or other people. However, there are several signs that indicate the presence of an old negative attitude:
- Periodic thoughts "I never ...", "it is always so with me ..." If you notice the word “never” or “always” in your speech or thinking, referring to a negative experience.
- Frequent complaints. Constant “I can’t do it”, “no one helps”, “I’ve been let down” – a sign that you tend to be a victim.
- Lack of new projects and initiatives. If you haven’t changed your job for years or tried something new in your life, it can often be because of deep programs that block risk and development.
- Feeling resentful or angry about the same past events. You may find that months or years later, you still feel annoyed when you think about a particular situation.
If at least one point responds to you, think: perhaps this very “poison” (old resentment, belief in injustice, disbelief in yourself) really “lives” in your head.
5. Five Steps to “Deconstructing” This Thinking Poison
Step 1: Acknowledge the problem. Unless we admit to ourselves that we are constantly holding an old negative belief in our minds, no change will begin. Awareness is the first key.
Step 2: Put it on paper. Try to write out all the complaints, resentments, fears associated with the feeling that “I was not given something”, “I did not receive something (a)”. When thoughts become visible, we become more aware of them.
Step 3: Switch to the author's position. Ask the question, “What can I do to fix the situation or move on without expecting mercy from others?” This destroys the illusion of self-helplessness and prevents the “victim program” from strengthening.
Step 4: Work in dialogue or with a professional. Sometimes it’s enough to talk about your old grievances with someone you trust—a friend or psychologist. If the case is complex, the therapist will help you find the root of the belief and work through it.
Step 5: Regular support for new beliefs. Just as a toxic thought “lives” for many years, a new constructive attitude (e.g., “I can change a lot”) also takes time to take hold. Practice affirmations, remind yourself of times when you coped yourself.
Conclusion
So, “the poison that lives in your brain for three years” is not just a metaphor, but a real phenomenon, reflecting the long-term existence of negative beliefs and resentments that generate feelings of helplessness and claims to the world. Such thoughts can undermine any initiative, strengthening the position of the “victim”, when we attribute all failures to circumstances. Meanwhile, there is another paradigm nearby – the paradigm of the “author of his life”, where a person is ready to take responsibility for his actions, change strategies and learn new things.
If you find the beginnings of such long-lived toxic programs, do not despair. The brain remains flexible (neuroplastic) throughout life. We can rewrite internal scenarios if we are mindful, engage in introspection and, if necessary, use the help of specialists. The key idea is not to let a negative attitude “populate” your mind for years, but to identify and eliminate it in time.
Remember that even if you don’t get enough (attention, support, material resources), you have the ability to learn and move forward. It is important to stop feeding your resentment, instead taking real action. Moving from “Why didn’t I get it?” to “What can I do to get it?” is like tapping a switch that changes the quality of life.
Your brain can be a beautiful garden where ideas and plans grow. Or it could be a "warehouse of old grievances" and disappointments. It's up to you.
