Jobs is famously known for dropping out of college after only one semester. After he left, he ended up traveling to India in search of spiritual enlightenment and returned to the U.S. as a Buddhist with a shaved head.
During this time, Jobs also experimented with psychedelic drugs. He is quoted in the 2005 book "What the Dormouse Said," by New York Times reporter John Markoff as saying his LSD experiences were "one of the two or three most important things I have done in my life." Jobs, pictured at left in 1977 after launching Apple, continued to practice Zen Buddhism.
