We practice beliefs even if we don't believe in them. Physicist Nils Bohr kept a horseshoe over his door to keep evil spirits out. When asked about it he said "hey, I'm not crazy, I don't believe in that superstition... but I was told by someone that it works whether or not I believe in it."

Buckminster Fuller reminds us that the goal of Utopian society should be total unemployment. He goes on to say that probably 20% of us are workaholics who want to go to work, and that we should give them the means to get everything done that needs to get done, and the rest of us will be free to persue science, music, art, maths, philosophy, horticulture, agriculture, spirituality, and everything else that has been replaced by consumption.
