Conclusions are based in time

From an interview with Demetri Martin:

We live in time. So any definition of success is bound up with time. With other things you can say, “Can I yo-yo? Can I juggle?” Usually you have a pretty small window in which to get your answer....the question is - “Will I enjoy this?” Because by enjoying it enough, now I have a nice big window. You can suspend judgment and make that hole very big. If I make my window ten days for stand-up, the conclusion is that I failed and that I’m not good at stand-up. If I make it ten years—if I just wait—the conclusion might be something totally different.
