I was pretty opened up by psychedelics around age 17, myself. I was pretty set on going to Med School before then, but I realized there were other things I liked a lot better. Just for fun I took a lot of Occupational Electronics in high school, and was pretty much the mad inventor in those classes. For example, one of my inventions was a working model of learned behavior, complete with stimuli, responses, reward, remembering, and forgetting. The neurologist's son who made a model of a single neuron was probably the only other person in the entire school who understood what I had done. No prize in the school science fair, because nobody understood I had built a (primitive) AI in 1967.

Psychedelics helped me see that I could do what I really wanted in life. It's been a blast so far.
