Taking in a nights and weekends side project when you’re already burned out in your day job is how you burn out even harder. I would absolutely not recommend this to someone struggling with burnout.
Thank you. I do feel emotionally drained at the end of the day. It is really hard to try and get in any work later. Also I always spend the evenings with my wife and kids till at least the kids go to bed which they did a little while ago :)
Possibly, but not necessarily. You burn out even harder if you do even more of the same kind of work that has burned you out already. The OP mentions: "if I have time, I might actually build something small", "I miss being a person who actually does stuff" and specifically "[directing] [is] work I don't want to do anymore". If, after work, you try doing completely different kind of work (within reason, of course), especially the kind that you've always liked, you might find some motivation and get reinvigorated. A hands-on side project might work the same way a work-unrelated hobby would.
