Ask HN: Advice for a first time CTO?

I'm constantly learning and reading about technical leadership but I'm curious what experienced CTOs on Hacker News would say.

I've been CTO at E-DealerDirect for about 6 months now and so far my biggest challenge has been letting go of tasks as we scale. I'm used to hoarding work and I've had to constantly train myself to delegate.

Outside of that scenario, what else is important? What skills do I need to learn that I may not have now?

Thanks for your input, Hunt
