@shepherd has captured my sentiments on this, existing in a similar boat of hobby fixation and jumping.
I found something tolerable that has enough day to day variation, [usually] weekly mental challenges that involve my problem solving skills (I'm a software project manager), and enough communication-based activities that I'm mostly okay with it nearly 10 years in. Caveat: I have been working remotely since late 2016 and this is probably a huge part of staying with it for me. I stumbled into this career path in 2008 via a temp role for sales admin at a software company that then became a full time role. That I then automated 90% of and earned myself an opportunity to move into support which eventually got me where I am now.
All that said - I am bored. I'd like to do something else. I don't know what that looks like. But I have [very slowly] accepted that it's okay to be bored and that all the new skills and hobbies I like to acquire and dabble in will slowly paint a picture of new, unconsidered possibilities for future opportunities. Heck, I joined up with a volunteer fire department last year and that is scratching so many itches: constantly learning, regular training and meetings, no call is ever the same, I get to leverage skills I've been developing and using for decades, I get some socializing, and I get to help people. I'm exploring this chaos with my regular, boring job and I'm hoping to find that balance.
