The Four New Friends You Need to Shake Up Your Life

Think of your BFFs like the supporting actresses in your life: They're always in the wings making the leading lady look great. But sometimes, the biggest laughs come from random, unexpected cameos. We recommend you always have one of these women rounding out the cast.

1. The Wingwoman

Who she is: The chick who can schmooze her way past any velvet rope, always has a great party trick up her sleeve and won't let you chicken out of talking to a hot guy. You might only call each other when you're newly single or your boyfriend is out of town ... and that's totally OK. In fact, the more opposite your personalities, the better.
Where to find her: Tap into your guy friends' girlfriends, cool people you meet at weddings, ex-co-workers with whom no more professional pretense is necessary, or a good friend's crazy/fun sister.
When to lean on her: When your ex is bringing his new model/professor/yoga instructor girlfriend to a can't-miss party.

2. The Mom-on-Demand

Who she is: Someone a little older and wiser who's been through everything - breakups, existential crises, career snafus, you name it. But since she's not actually your mom, you can spill some of your darker secrets with impunity. She's maternal by nature, so you'll probably get plenty of dinner invites with her fam.
Where to find her: At your office happy hour, a volunteer organization or at a gathering of your extended family.
When to lean on her: When you really miss talks over your mom's homemade banana bread.

3. The Superconductor

Who she is: More than a career mentor, this schmoozy woman is like the de facto mayor of the social scene. She's only a few rungs higher than you on the corporate ladder, but she seems to know everyone. She's happy to help hook you up with someone who can give your career a boost, and she feeds off the appreciation and awe you exude in her presence.
Where to find her: At networking events, women's business seminars, at alumni association events, or through a family friend.
When to lean on her: When you need career CPR -- you lost your job, want to jump ship, or need a personal introduction to the head of HR at your dream company. The key is to make sure you don't get in touch only when you want something. Schedule monthly drinks or coffees, and send links to articles she might like or suggest people on your level you know that she could hire

4. The Thrill-SeekerWho she is

The spontaneous, sensation-seeking globetrotter. You suggest bowling, she suggests an "amazing" place in Argentina where you can horseback ride through vineyards totally naked. While she's not the most stable type (good luck getting her to return your e-mails when she's on an ashram), no experience is too nutty or extreme in her book -- and she's psyched to help you write an exciting new chapter in yours.
Where to find her: Yoga or dance class, on an international flight, touring with her favorite band, or the unemployment office.
When to lean on her: You're beyond bored. Or you're looking for a travel buddy to explore somewhere your close friends would never set foot.
