Inspired by mnmal.org's 40 rules, I give you Ben Simon's rules for life:
Rule 0: Love your wife.
Rule 1: You're going to die. (In other words: life is short, cherish every minute of it.)
Rule 2: Everything but death is fixable. (Not exactly true, but a solid rule of thumb.)
Rule 3: Time is the most precious resource. (See Rule #1.)
Rule 4: Consider the 1 year test. (Will this event/activity/item be important in a year? If not, consider Rule #3.)
Rule 5: Be Honest. (If you broke it admit it. If you don't understand it, admit.)
Rule 6: Consider contribution, not blame. (Not "who's fault is it?" but, "how did each of us contribute to this problem?")
Rule 7: Your taste will exceed your skills. (So, practice, practice, practice.)
Rule 8: Go to bed angry. (A crisis often shrinks to nothing when considered on a full night's sleep.)
Rule 9: Find Flow and you'll find happiness.
Rule 10: When communicating with others, prefer pictures over spoken words. Prefer a working model over pictures.
Rule 11: Make a list. Prioritize. Work on the first item. Forget about the rest until the first one is complete.
Rule 12: Be Prepared.
Rule 13: Smile.
Rule 14: Consider it an experiment. (There's no failure with experiments, just more data.)
Rule 15: Always completely pay off your credit cards at the end of the month.
