To invest successfully over a lifetime does not require a stratospheric IQ, unusual business insights, or inside information. What's needed is a sound intellectual framework for making decisions and the ability to keep emotions from corroding that framework. You must supply the emotional discipline.
Discipline does not mean suppression and control, nor is it adjustment to a pattern or ideology. It means a mind that sees 'what is' and learns from 'what was'.
What is the next step, the practical application? —I will answer that the absolutely vital thing is to consolidate your understanding, to become capable of enjoyment, of living in the present, and of the discipline which this involves. Without this you have nothing to give.
Either you think, or else others have to think for you and take power from you, pervert and discipline your natural tastes, civilize and sterilize you.
It has been said that the great scientific disciplines are examples of giants standing on the shoulders of other giants. It has also been said that the software industry is an example of midgets standing on the toes of other midgets.
