Any unwillingness to learn mathematics today can greatly restrict your possibilities tomorrow. - Richard Hamming

A second reason the systems engineer’s design is never completed is the solution offered to the original problem usually produces both deeper insight and dissatisfactions in the engineers themselves. Furthermore, while the design phase continually goes from proposed solution to evaluation and back again and again, there comes a time when this process of redefinement must stop and the real problem be coped with — thus giving what they realize is, in the long run, a suboptimal solution.

is a thin line between having enough self-confidence and being overconfident. I suppose the difference is whether you succeed or fail; when you win you are strong-willed, and when you lose you are stubborn!

It is well known the drunken sailor who staggers to the left or right with n independent random steps will, on the average, end up about √n steps from the origin. But if there is a pretty girl in one direction, then his steps will tend to go in that direction and he will go a distance proportional to n. In a lifetime of many, many independent choices, small and large, a career with a vision will get you a distance proportional to n, while no vision will get you only the distance √n. In a sense, the main difference between those who go far and those who do not is some people have a vision and the others do not and therefore can only react to the current events as they happen.
