O's 101 Best Pieces of Advice

All the wisdom you need to do almost everything better...and while you're at it, feel happier, healthier, more chic, less stressed, and ready to take on the world.

How to Eat Healthier

Take baby steps: At 21, after years of eating fast food almost daily, I set a goal to eat healthier fats and less sugar once a week.

Embrace variety: Add two new foods to your diet weekly (seriously, try quinoa). I hated vegetables, but taste buds do evolve.

Eat food in its original state: You'll automatically eat better. Cooking from scratch just requires planning—and a slow cooker.

Don't stress over slipups: If you're eating healthy 70 to 80 percent of the time, it's okay to grab some fast food once in a while.

How to Have More Fun

Smile and you'll make everyone's day a little brighter, including yours. I smile 24 hours a day, even when I'm sleeping.

How to Get Past Emotional Pain

Everything we experience—no matter how unpleasant—comes into our lives to teach us something. To move on from something difficult, look for the lesson. Start by asking yourself: If this is the way things are supposed to be, what can I learn from it? Think about how you may have contributed to the painful experience, or if there was anything you could have done to prevent it. Often we don't realize the lesson because we'd rather avoid reliving the pain. But once you allow yourself to reflect on the sadness, anger, guilt, or shame you've been hiding, those feelings will begin to subside. Yes, someone hurt you. Once you've forgiven them and let go, you can move forward and begin creating the life you desire.

How to Say No

Say this to yourself: "I'm not required to do something simply because others expect it." Then look the other person in the eye and say, "I can't do it."

How to Lift a Wine Stain, Stat?

Blot the spill, then place a white cotton towel beneath the stained area. Apply a mixture of five parts warm water and one part enzyme laundry detergent. Tamp with a second towel until the stain disappears.

How to Fix a Clogged Drain?

Drano will do more damage than good. Instead, use straight Clorox and let it sit for four hours without running the water. The bleach will break down whatever is clogging your drain.

—Keith Bienvenu national president of Plumbing-Heating-Cooling Contractors Association

What's the Must-Have Car Tool?

Traditional jumper cables are great—until there's no one around to give you a jump. Portable jump-starters don't require the help of another vehicle. I particularly like the DieHard models from Sears.

Which hair dye should I buy?

Ignore the model on the front of the box and turn to the haircolor chart on the side. That will show the color you'll end up with based on your natural shade. And always buy at least two boxes. There's nothing worse than running out of dye halfway through.

—Michael Canalé, owner of Canalé Salon, in Beverly Hills

How to Not Sweat the Small Stuff

The thing that's grand about spending your time thinking about the universe is that it makes you feel insignificant. I don't mean that in a bad way. If you understand that we've now discovered entire solar systems that contain planets similar to Earth, and that those are just the ones we know about, since most of the stars we've looked at are within about 300 light-years of Earth and the distance to the center of our galaxy is nearly 100 times that—then you realize that the laundry you've left undone and the dumb thing you said yesterday are about as significant as slime mold.

How to Sleep Together

You need to compromise. He gets to have the window open; she gets an electric blanket. The person who falls asleep to the TV uses headphones; the person who needs total darkness uses a mask. If she goes to bed later, she puts on her pajamas early, so she's not loudly opening dresser drawers. Blanket thieves get their own duvet, and snorers can seek medical intervention—or buy their partner a pillow under which to bury her head. And make your bedroom a sanctuary. Paint walls pale blue or green; remove all stimuli (books, gadgets, photos); light candles with a comforting scent; never keep a desk in the room. This is the place where you engage in your most intimate communication, both verbally and physically. So take the time to make it conducive to both activities.
