Should you find yourself in a chronically leaking boat, energy devoted to changing vessels is likely to be more productive than energy devoted to patching leaks.

Your private journal should record the way you face up to challenges that beset you. Do not suppose life changes so much that your experiences will not be interesting to your posterity. Experiences of work, relations with people, and an awareness of the rightness and wrongness of actions will always be relevant. Your journal, like most others, will tell of problems as old as the world and how you dealt with them.

No problem is so big and complicated that it can't be run away from.

If you can't make a mistake, you can't make anything.

We can't solve problems by using the same kind of thinking we used when we created them.
