I’ve made plenty of mistakes, I’ve had setbacks, made mistakes in that sense. I don’t consider them setbacks. If I work for a while on something, and find out that my idea wasn’t right, well okay. It’s not exactly a setback, I’ve explored that path. Down that particular path doesn’t lead anywhere, and so I’ve done something. To me it doesn’t seem like a setback. It’s a mistake, you might say. So I go off some other way, so it’s certainly not painful. But I’ve done plenty of things that aren’t right that I find out about, made missteps. The idea is to try to figure out the best thing to do, but stay self-critical. As soon as you find you’re wrong, backtrack and do something else.
