I think there are things that you look for when you're younger, and you think they are going to make you happier or make you feel complete. That's not going to happen, and it's really about living the moments. Eventually, you reach a point when you're at ease with your life and don't have any unrealistic expectations.
I think the rejection - if it's taken in the right spirit, it can make you a better person. And I think that is what I've always striven for. If one thing didn't work out, a project or anything, it doesn't mean that I lose my own confidence. In fact, I give myself a lot more confidence and opportunities.
