How do you stay motivated?

Does anyone else struggle to stay motivated to actually start/work-on/finish projects? I’m struggling with this so badly that I’m starting to question if I actually enjoy this as a hobby.

For example, today was the first opportunity I’ve had to be in my garage in weeks. A relative had recently gifted me some new tools that I needed to look over. I spent 2 hours working on one to the point I realized even as “free”, it wasn’t worth it, and my time/sanity is better spent buying something new. Fine.

Spent the next 2 hours “organizing” stuff from the last time I did something. Now I’m so mentally and physically tired that I don’t feel like staring anything new. I have hours left in the day that I’ll probably piss away on something else, and the next time I come back for the shop it will be the next cycle of “well I need to clean/plan/organize before I can really start anything”.

Sorry if this is a bit off-topic and whiny… just trying to see how others have dealt with this.
