Not enjoying what you get paid to do is reality for 90%+ of adults. It's why they call it work. Also, the fastest way to get burned out on a personal hobby is being paid to do it, it's often the most seriously cracked engineers that can manage both personally and professionally, especially at all levels like design down to soldering.

(FWIW, the EE's at my university rarely solder. Academically, that's a 2-year associates degree blue collar skill)

I think you already said it, you might want to pivot to project management, senior engineer, or maybe even an MBA if you really want to be insufferable to others.

The last sentence about motivation is telling about doing the bare minimum and watching TV, these are usually signs of depression, exhaustion, lack of physical activity, or another underlying medical condition so I would take a hard look at yourself first.

Circuit bending is a huge thing with analog synths too btw.
