This absolutely terrifies me.
> The simplest hack here: wake up earlier and use your first (and best) 2-3 productive brain hours on your project then go to work. You'll use your best performance (refreshed, alert, not tired) for your project while still not being fired.
I really, really enjoy my sleep :). This is certainly very practical advice, but it requires that I'm disciplined enough to go to sleep earlier the preceding night. That's difficult but certainly possible.

It's incredibly tempting. The problem (that actually isn't a problem) is that I enjoy my full-time work as well.
Thank you for the advice!
