After earning a Ph.D. in biochemistry, Jim spent several years learning how businesses are run while working for a small biotech company. He started investing about a decade ago, making the same mistakes most people do. Finding the Fool and changing careers several years ago to work here, he's managed to improve his investing process while developing a messed-up-expectations approach. With this, he tries to take advantage of times when the market is either too pessimistic or too optimistic about a company's prospects. (It helps to have a long-term perspective.) Right now, besides his day job as an analyst for Motley Fool Stock Advisor, he's in the process of obtaining the CFA charter.
