Is this the ennui all the kids are talking about? Angst? What's wrong with me.

I've tried before to get input on this, but online it doesn't go anywhere and IRL people don't seem to understand. Thought about putting it in the /~finance area, but I don't know that it's really a finance issue, plus things there seem to be wider-scale financial in focus. And there's no /~advice page, so here it is:

I feel like I should be making more money lol. Now immediately, that sounds greedy or either capitalistic/anticapitalistic, depending—I know it does, but hear me out. I have a great job that pays ok but not great, and tons of free time; in my mind, and if I'm being honest in my field, chasing a 5% raise is low ROI and low likelihood of even happening. There is little room for vertical movement, but enough security that it seems crazy to make any changes. Post-college, I have had a pretty varied career background, I am very good at editing, research, training, tech, etc. but I am not an "idea person" and I don't have a lot of marketability or self-promotion ability, it seems like (also no coding abilities, which is always a suggestion; I've tried, believe me, but my brain won't do it). I'd rather edit your book than write one of my own, not because I'm afraid of rejection or can't commit to doing something/run out of steam, but because the steam just isn't there.

I don't feel the need to change careers, but I am also feeling super unfulfilled. I've worked on doing things to try and fill that gap, hobbies/other pursuits/etc, but I am haunted by the fact that I am using such a small part of my bandwidth, when it seems like I could be outputting at 2x or 3x and earning similarly. I've applied for contract work, freelance, all that stuff, but it is spotty pay at best—what I want, short of a medieval patron/wealthy benefactor, is a second job I could do on top of this one. Which leads me to side-hustle-type rabbit holes on starting an Etsy shop/a YouTube channel/a Patreon page. But when it comes down to it, I don't actually feel any passion about doing any of those things, and I can't get a narrow enough niche figured out to even come up with a potential audience. I've avoided specializing because I wanted to do all kinds of things, and now I've done that, and I feel like maybe it was a mistake. I just want to have the resources available to do what I want. Bills are paid, life is good, but I feel like I am spinning my wheels: even writing this out is like a roller coaster of feeling shame that I'm not satisfied or that I'm ungrateful, then being frustrated I can't make it happen the way I want, on my own.

Because see, I didn't say I deserve more money; I want the opportunity to earn more money. There are a ton of things I would be perfectly happy doing for a living, or for a second job. And more money might not even help—if I was a trust fund baby I be in a similar situation. But what the fuck should I be doing then? I guess what I really want is for someone to say "Hey, I need this job done, I'll give you $XXk a year to do it" like it's 1980, and then I know I am serving a purpose? And I wouldn't feel guilty about time left over, because the job is Done. But part of me is afraid that, even if that somehow magically materialized, I would feel the exact same way I do now.

so what do tilderinos?
