Is it luck ?

Last month, I was reading a book, which is one of my all time favorites. I have read it many a times, thought lemme read it once more.

There is an interesting event mentioned in one of the chapters.

A woman meets a famous painter in a busy street. She greets him and asks him to sketch something for her. The painter immediately comes up with a sketch and hands it over to the lady.
He also tells her, its worth a million. The surprised lady immediately asks, worth a million?, it took only 30 seconds to draw that out, to which the painter replies, it took me 30 years, to draw it in 30 seconds.

Cute, very cute isn't it.

There are many such incidents where in I have repeatedly done the same task again and again to gain familiarity with it. But the real twist in tale comes here. What if we do not have the opportunity to try the second time.

Assume a programmer is trying to code a bit @ workplace. He fails first time, betters second time, but still fails and starts for the third time. But what if his first/second time failure is fatal? What if there is no second/third time chance for him, since he may have lost his job by then.

I feel here luck comes into picture.

You need to be lucky enough to find a proper place and your enthusiasm to try must not come down. Else, the case can be drastically different
