When I was fourteen, my father was so ignorant I could hardly stand to have him around. When I got to be twenty-one, I was astonished at how much he had learned in seven years. See what happens when you "know it all", at any stage of life? Farther down the track you may see clearly how certain personal opinions, held onto too tightly, could be fogging up the view, and providing incorrect insight. Prosperity is the best protector of principle.
A man cannot be comfortable without his own approval. There is nothing more satisfying than that sense of being completely "at home" in your own skin. When you achieve that as a natural state of "being", then you can finally look beyond yourself and fully contribute all your talents to the world.
Time cools, time clarifies; no mood can be maintained quite unaltered through the course of hours. When you make a decision to "be" a particular way, you can count on change and external circumstances to come along which will challenge that decision. Remain vigilant after declaring a major decision and manage yourself in relationship to the goal. Set up structures that support you staying on target.
I have spent most of my time worrying about things that have never happened. Worrying is not an action! In fact, it is action that alleviates concern and dissipates worries. Take more actions when you feel that worry is creeping in to steal your time. It need not be a huge action, any action in the direction you want to go will do.
