Making any decision is often better than analysis paralysis:
The kids with the wealthy, well-educated parents who graduated near the top of their high school class tended to make more money as adults than the blue collar kids who figured out early on that formal school wasn't really their bag.
But Judge and Hurst also looked at something else. This is where things get interesting. A unique subset of people in the study did not follow this pattern. By the time they reached their middle years, some sons and daughters of roofers and plumbers whose grades (ahem) made the top half of the class possible, still ended up making 30-60 percent more money each year than many of their more privileged peers. What this select breed of underdogs had in common was nothing but a unique set of personal beliefs (stemming from emotional stability, internal locus of control, self-efficacy, and self-esteem) about their ability to shape the future. Those beliefs translate into the ability to choose one course of action (entrepreneurship, less prestigious career path, etc.) while quitting others.
Making any decision now is better than making the "right" decision late or never.
(Bonus question: does this bother you? If so, why?)
