So Eli will tell you a post doc story. Way back when lasers were new and dinosaurs (or at least very old photochemists) roamed the earth, Eli had an idea and went and told it to his boss over Torten und Kaffee (it was in Germany). The boss told Eli not to bother, it would never work, here's why and don't waste your time and my money doing it.
Being a young bunny, Eli didn't do it until about a year later what shows up but the very thing done by a big shot in another lab, and everyone starts talking about it. So Eli goes to the big guy and says: See, I was right. The big guy simply said:
You didn't do it.
There are things that you just gotta do.
