I've had self-esteem issues for a really, really long time. Plenty of people think I'm ugly, and plenty of people don't. But there's a moment when I'm modeling where I forget about my self-esteem issues and focus on what the photographer's telling me - and I feel pretty. And in that sense, it's selfish.
Now I see other kids and their parents, and I compare them to my dad. Our dad was a really normal father when he was with us. We would get grounded if we did something bad. He would ground us. He wouldn't call it grounding; he'd just say, 'You're on punishment.' Sometimes we'd be on punishment a lot.
