Do not give up halfway

Imagine primitive man who produces fire by friction. To fire appeared need to scroll the wand, e.g., 365 times.

And here is our ancestor with you, rising early in the morning, twisted wand once, and ran to hunt for the mammoth. The next morning he twirled his wand again, and ran to hunt the saber-toothed tiger.

Will there be a fire on the 365 day? Of course not. But if he scrolls wand 365 times in a row without stopping, he will fire. And the most interesting, then it is no longer necessary to twist the stick every morning. The main thing - keep the fire.
But how many people drop out of the business one step away from success, scrolling wand only 100, 200 and even 364 times. Forces took a lot, but the result is not obtained.
