Don Melton on why, when he looked upon the breadth of his WebKit and Safari work at Apple, he retired:
I accomplished far more there than I expected. And I had no dreams of greater power and glory, if such a thing were available to me. When I looked inside myself, I didn’t see ambition or even drive to continue. [...]
Better to step aside and let others have their turn. So I did.
Also some great stuff on the Monday morning meetings at Apple, and working there in general. Read it all.
