I see a wiser person than when I was younger: having babies and passing 30 were the turning points. What women in their 40s - I am 39 - lack in gorgeousness they make up for in wisdom. I love ageing despite the drawbacks - thinner drier skin.
The hardest part was when I was in high school not having a job and always being broke. I had to get to auditions without a car. I either took the bus or walked.
