What if your older self could talk to your younger self, what would you say? What advice would you give yourself? Oprah asked celebrities to pen letters to their 25-year-old selves. The results are interesting.

Seventeen celebrities took the time to offer their younger selves advice. The letters published on Oprah.com come from a range of well known people including Actor Michael J. Fox and TV Sportscaster/Former WIVB-TV Reporter Pam Oliver. (Oliver worked at Channel four in Buffalo in the late 1980's.) Here's what they and a few others had to say:

Actor Michael J. Fox: "When the unexpected and inconceivable intrudes on life, and it will, deal with life's actual events—don't obsess about perceived eventualities. "

TV Sportscaster Pam Oliver: "Television journalism will be humbling. Expect to get kicked in the teeth a time or two."

TV Personality Katie Couric: "It pays to know your stuff about sports. A lot of guy talk and bonding happens over big games and great athletes, so it helps if you're not clueless."

CNN Anchor & Cheif Political Correspondent Candy Crowley: "Be brave. Most times the answer to 'What's the worst that can happen?" is "Nothing you can't handle.'"

Actress Carrie Fisher: "If there's a choice between companionship and anything else—especially career—choose companionship. It's the only thing that has the potential to last...  Fame is not acceptance."

MSNBC "Morning Joe" CoHost Mika Brzezinski: "Stop taking everything so personally. Don't waste your time wondering why somebody didn't return your call or spoke gruffly to you."

What would I tell my younger self?  Growing older doesn't mean you have to take life so seirously.  Don't stop having fun and hanging out with friends because the house needs cleaning.  Enjoy your life.
