This weekend, set aside a half hour to completely waste. The only limitation is that you have to waste it actively instead of passively. Don’t watch TV or listen to music or nap on the couch, waste it doing something impractical.
Use the time to imagine the stupidest, most foolish idea you possible can. Use it to sew a windbreaker for a monkey complete with tail hole. Write a proposal for the worst movie ever. Break new ground in hot dog technology. Solder a stained glass Pauly Shore. Make up an imaginary friend who gives you bad advice. Come up with a reality show idea that would only appeal to people over 75. Improve the rubber chicken. Invent a machine to re-straighten used staples.
Actively wasting time is called playing. Try it for a while this weekend.
