Ambitious mathematicians and scientists are goal-oriented. They want to leave their mark. Solve a classic math problem. Found a new branch of mathematics. Make a great scientific discovery. Trigger a paradigm-shift. Dream up a new deep scientific theory.
More often then not, they fail. They die unfulfilled.
The lucky or talented few succeed. But then comes the big letdown. Having reached the goal, what do they do with the rest of their life? They lose their sense of purpose. Become eccentric. Become self-appointed pundits.
Whether you succeed or fail, secularism offers no real personal fulfillment.
