I Don't Know How Hard Someone Worked

I wanted to know your thoughts on setting up programs or ability to reflect upon how hard someone works. The chapter you have about Van Gogh where basically it ends is like, I didn't know how hard he worked. You hear about him sort of meandering through life in a variety of different ways. Is that the best way to sort of encourage people to try many different things is to judge how hard they are pouring themselves into it?
