“When the entire household goes to bed, I do curl development for 2 more hours.”
I've had a few personal projects where I've spent several hours in the evening working to get it off the ground. What I've found is that my mind is so activated/stimulated that I then struggle to even fall asleep as the code is still dancing in my head. It's a real trade-off I have to make - stay up late to begin with to code on something and then another 45-60 mins to even fall asleep.
