One last R.W. Hammings insight:
Ability is not enough. You must be deeply committed.
“Perhaps the ablest mathematician I have watched up close seldom, if ever, seemed to care deeply about the problem he was working on.
He has done great deal of first class work, but not of the highest quality.
Deep emotional commitment seems to be necessary for success.
The reason is obvious.
The emotional commitment keeps you thinking about the problem morning, noon and night, and that tends to beat out mere ability.”
