“The most successful people have failed more times than you have tried”

Yes. I like to think that all of the people above could have solved most of the same problems, albeit in wonderfully different styles, but what really guaranteed success was a commitment to just keep at it.

Edit to add: Still, the styles matter a lot! For one thing, they greatly influence which problems each person is interested in. Also, the style you solve problems with colors what your final output looks like, which is perhaps more obvious in engineering than in mathematics.
