Вы не можете выиграть игру, правил которой не знаете - David Allen

The big problem is that your mind keeps reminding you of things when you can't do anything about them. It has no sense of past or future.

We’re never really taught that we have to think about our work before we can do it; much of our daily activity is already defined for us by the undone and unmoved things staring at us when we come to work, or by the family to be fed, the laundry to be done, or the children to be dressed at home.

We can never really be prepared for that which is wholly new. We have to adjust ourselves, and every radical adjustment is a crisis in self-esteem: we undergo a test, we have to prove ourselves. It needs subordinate self-confidence to face drastic change without inner trembling. — Eric Hoffer
