I didn't really feel like I matched any of Schott's personality profiles but there were a couple of things I like. First a quote:
Wealth accrues from a pattern of generally right behavior, not from trying to extract the maximum profit out of each and every situation, since one never knows what the maximum might be.
Which I liken to my baseball analogy: it's better to hit singles and doubles, get men on base and move the runners rather than hit a home run at every at bat. The next part I liked was Appendix B: Net Present Value: A Calculation for Confident Buying. For awhile I've been looking for methods to calculate values of companies that is short of getting an MBA. This is a great 3 page start.
