That nerve racking moment of running a command, especially when deploying code. It at once terrifies and excites me.
The only thing I can compare it to is performing in front of an audience. When I go out to play a piece from memory, I worry that something might go wrong. Really worry. And often something does “go wrong” — a memory slip, a buzzed note, a failed chord. But you know what? You recover from it, you continue to play and then you finish the piece. Performing a couple times makes you realize that course correcting is all that performance is. We're not an mp3 player, we're human.
That makes me think of programming — you can't be perfect when running a command the first time. There's many fixes and running a command afterwards to get it to work. It's all course correcting in the end.
To enjoy that process...
