I am surprised, happy and envious (at the same time) when I see people with passion ( towards work in particular and about anything in general ).

Ps: Not implying anything, but I partially remember this sentence from one of the finest articles I had read on a tennis match writing about Sampras’s loss and a comment about the opponent (whose name I forget) :

He was quick, perfect, [etc] everything that Sampras himself once was but can no longer be.
