I went to the University of California at Berkeley. I had many opportunities to not only drink alcohol, but smoke marijuana, snort cocaine and drink psychedelic mushroom tea. I did none of it. At the time I thought it was because I was afraid of addiction, descent and ending up dying in a gutter somewhere. Now I realize that I've avoided many things, not out of fear of death, but out of fear of life. I rejected opportunities to experience being drunk or high because I was afraid of the pain of living. I have, in fact, passed up many opportunities to travel, explore, love and try new things beause of that fear.
I find life uncomfortable enough without taking risks to experience more of it.
