Someone asked me how I was able to develop such strong intellectual discipline.

My secret is that I'm dysfunctionally conscientious.

It's a crippling personality trait in many ways, but I've learned to use it to my advantage.

I use that to create clear, always-rules commitments to myself that I'd feel deep shame for failing to abide by.

If you have a monster that's always chasing you, you might as well use it as an opportunity to get fit!
