It becomes a huge part of your identity. When you doubt your work, you naturally start doubting yourself. I'm not sure that there's a way out of that cycle.

And I'm going to want to give it to him. Having a baby through this forces you to focus eventually. If I screw this up, a lot more could be at stake.
