Profession: Actress in this month's Iron Man 3.
When did you start golfing? At age 10. My dad took me to the golf course on the weekends.
Experience: I took a year off after high school and played in tournaments all over Europe.
Highlight reel: A couple of years ago I was the only female celebrity who participated in the Bob Hope Classic. I played from the men's tee!
Favorite courses: The European Club in Ireland, The Royal County Down in Northern Ireland, and my own club—The Saint Andrews Golf Club in New York.
I love: My TaylorMade Rossa putter.
I wish:You could wear golf clothes that looked good but didn't look like you were going to play golf.
I used to: Swear in French on the course. Nobody knew what I was saying.
Now I say: Golf is just like life. You can be playing great, and then have a terrible hole. You have to forget what went wrong and keep playing.
BEGINNER'S TIP: "Find a girlfriend to start with you," says Szostak. "It's intimidating when you don't know how to play.""Meredith Jenks"
WILLA HOLLAND, 21
Profession: Actress in the CW series Arrow.
Obsession: Playing the ukulele.
Why the ukulele? When I moved to Vancouver to film Arrow, I had nothing to do on my days off. A friend said, "Get a ukulele. If you can't pick it up, then you've just wasted 30 bucks. Big deal."
When I started, I thought: I can't do it. I have no hand-eye coordination.
Then I realized: Any human can pick up the uke. The kind I bought, an Emus, came with a booklet of chords. I learned those, then and there.
Work in progress: My biggest problem is I can't play and sing at the same time yet.
Accessorizing: I use a shoestring as a strap.
Music is ... One of my favorite things. I've always envied musicians. Now I've found something that I can play.
What's next? The banjo!
GET STARTED! Holland's tip: "Look for a ukulele that's well-crafted but cheap. Think wood, not plastic.""Meredith Jenks"
