It's got to be the best intellectual exercise out there. You're seeing through new situations every ten minutes. In the stock market you don't base your decisions on what the market is doing, but on what you think is rational. Bridge is about weighing gain/loss ratios. You're doing calculations all the time.
Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite sea and so make it finite. The result is mental exhaustion. To accept everything is an exercise, to understand everything a strain.

I know I need to exercise. For some people, exercise is like breathing; for others, like me, it takes effort. Exercising is what I need for my metabolism and for a better sense of well-being.
Whatever discipline you exercise should be based on the goal your child is eventually to reach, namely, freedom and happiness. I would show him towards what he is growing, his ultimate fulfilment, and help him to adapt himself to that. In everything that you do, you should keep the goal in view, and hence your discipline must aim at helping the child to realize that at a certain stage he will be above all discipline.
Almost every man we meet requires some civility; requires to be humored; - he has some fame, some talent, some whim of religion or philanthropy in his head that is not to be questioned, and which spoils all conversation with him. But a friend is a sane man who exercises not my ingenuity, but me.
