10. You pay your mate in trade
It's been a long day with the band saw, paint roller, whatever—the time has come to cash in. If you did the work solo and your other half comes home to see something actually accomplished, you'll get major props, so milk your hard labor for everything it's worth. Request a massage—a real one, not some squeeze-squeeze, pat-pat over the clothes—the full Monty, on the bed, with lotion and that nice aromatherapy candle burning. Of course, if you both hit the wall on the project, you'll have to settle for "I'll do you if you do me"—still a win-win. Bonus tip: Never knock yourself out to the point you'd rather be put in traction than reap these rewards!
