Did them, the games, the websites, the failed startup thing.
I just do other things now.
Building finance stuff during the day, doing little computer outside work (a bit of 3D printing here and there).
It’s fine. My career’s fine. The work doesn’t suffer from it.
Do I have the spark? Idk, I feel I am too old for that spark shit. There is work to do, I do it. If it’s tedious, I’ll drag me feet a while, but eventually it’ll be done. It’s just work.
That said, I think your day job is more enjoyable when you see your work as a craft. It becomes less of a chore, you feel more engaged, and generally happier, which ultimately has a positive impact on your work and your colleagues. This has been my very fuzzy experience over the years, going through periods of both, but there are no definitive perspectives either way.
