I was never as cocksure again after that first LSD inspiration. Especially with fame and reputation. You become very uncertain, you have to follow your own act. I never did get that kind of spontaneous cocksureness back again. It's like going from being the observer to the observed. I had been used to being invisible when I was young. After I became well-known, it was very hard to be anonymous in the world. Of course, at first I liked all the attention. Suddenly, good-looking girls were interested in me! Wow! I couldn't believe it.
