There are always seasons to a career and perhaps always the grass is often greener, you're often looking at other people's careers going, "Damn, they get all the good roles. Why didn't I read that? Why didn't they ask me to do that?"

Look, how many stories have I broken? Hundreds. How many have proved to be untrue? There isn't one.

When I think about it like that, it feels like a burden. But that won't mean I'll be single for the rest of my life - I hope. I feel very settled with myself in my world.
