Here's one, emphasis on lifestyle.
Unless you're the POTUS, you can probably do this for a couple of weeks before irreversible long-term consequences may arise:
#1 U.L. RULE: Do not do anything "expected" of you.
Forget work, of course.
Don't return phone calls or emails. When you run into someone who wants to know why you didn't return their phone call or email, don't apologize sheepishly (which is what they're expecting you to do, right?) -- just look at them and smile and tell them you "just didn't feel like it."
If you're ditching work, go ahead and call and cheerfully announce you won't be in for a couple of weeks. If your boss wants to know what the hell is going on, just shrug and say, "I don't know, it's crazy though, isn't it? Well, see you later."
If you're an anti-social zealot who screens every phone call and goes out once a year against your will, go out every single night of the week and do nothing but chat with friends and family from dawn until dusk.
If you're the Parent of the Year? Oh boy, the possibilities are endless, and so much fun. Let your kids get up for school whenever the hell they feel like it (if
they feel like it). If the school calls to complain, just say, "Uh huh, uh huh. Yes, they are
late a lot these days, huh?" Forget nagging them about their homework, or bedtime. When they come whining for dinner, hand them a bag of cheetos.
If you're a college student, cut class -- unless that's what people (including yourself) expect
you to do, of course -- and couchsurf your way to Mexico.
If you're normally the life of the party, go to a gathering and say absolutely NOTHING. If you're shy and retiring, show up somewhere in a pimpin outfit and flirt with everyone -- man or woman -- present.
If you're an early riser, stay up all night.
If you surf the net all day, don't go anywhere near your computer.
If you never curse, swear like a trucker every chance you get.
If you're normally a lazy, unfocused SOB....do nothing but work. Work your ass off. Stop only to **** & shower once a day. Ignore your significant other, don't take calls from your mother, don't so much as glance at the paper or the news, don't open any non-work-related emails, don't even make eye contact with anyone unrelated to your work. Do nothing but work from the moment you open your eyes till you lay your head down to sleep.
If you live and breathe spreadsheets, pick up some paint and surprise your wife with an afternoon body painting session.
If you're an incurable skeptic, head to your local astrologer and vow to take everything she has to say as the gospel truth.
Kids are grown, spouse is history, and you haven't had a date in years? Hire a gorgeous, top-of-the-line escort and have an incredible night on the town. If you can time this to coincide with the family holiday party, much the better. (Don't spend all night there, though; just pop in and make a brief appearance. When they ask you how you met Tony, just smile, raise an eyebrow, and change the subject.)
And here's the diet part: If you worry about everything you put in your mouth....don't. And if you never, ever diet? Go raw, of course! If your friends and family attempt an intervention, you'll know you succeeded in grandly pulling off the Unexpected Lifestyle. Congratulations.
