Dude....you know I'm being serious because I never say, 'Dude'. First, you sound like you have a lot of interests and you should be super grateful for that because some people are pretty vapid and don't.
I know first hand EXACTLY what you're talking about because focussing on one thing has been a struggle I've endured my entire life (I'm 53). You feel like a quitter when you move on and you question your decisions because you're never quite sure, but here's the thing...even if you're 27 now, chances are very high that when you're my age, you will still be thinking about these same things. The difference over time is that you won't worry so much about it and if you're smart you will nurture all those things you like and try to do as much as you can to satisfy some or all of them when you can. If you have to take a job you don't like, look at it as a means to getting something closer to what you are more meant to do. Don't do anything that others expect you to do or feel you should be doing because that won't make you happy.
I have had multiple careers and jobs where I was able to do exactly what I wanted to do...dream jobs, but even dream jobs stop being fun and when that happens and you have it in you, you move on to something else--one of your other interests. I've done it over and over in my life and am starting over again. Just keep growing, learning and believing that you can really have what you want and if you get tired of it, it's okay to stop. You have to also remember that old saying, "You've got to pay your dues." Sometime the dues are to others and other times they're to yourself.
Yeah, I've been through the whole picking up a job to see if it will possibly lead to an interest or idea for what I want to do in the future. And I've thought many times "I might want to make a career out of this" but when I start doing it, I slowly get burned out and lose interest. I stopped drawing for awhile, because I was forcing myself to do it too often, and I just stopped enjoying it as much.
Also, being in a relationship, I feel like my feeling like this is affecting my spouse as well, and I also want him to be happy. I want to keep up my end, and be someone who can support us, but at the same time, I don't want to get stuck working a shitty low-paying job again and feeling like shit. I'm not particularly good enough at one thing to get a nice job. The only reason I had a nice job in the past, was because of some connections, and I learned how to do it on the fly, and didn't need all the requirements that they usually expected.
The only godsend right now is the existence of Steemit and crypto related social media, because sitting at the computer and sharing different things that I'm in the mood to do each day is what I really just want to do forever. The problem is, not all those things are high quality enough to be my "career" so that's why I want to focus on one thing for the majority of my time, get better at it, and share it. I just don't know what that is yet. I'll figure it out though.
Thanks for telling me your feelings and story though. I really appreciate it! [:
When you find the thing that you think you want to do and see that there's a job that actually fits that description, you will be surprised at how far you can get in the interview process and possibly nail the job if your enthusiasm shows. That has more weight than experience. I've gotten really good jobs with little to no experience only because I did a little homework about the place or just talked about how this is what I really want to do (even if you quit after a year). My last job wasn't even hiring, but I wanted to work there and just got in touch. The one before that was a pretty prestigious events job that I desperately wanted and knew there were others more qualified...I made little paper stand-up models and used them to explain a public art project I had thought up and made sure their company logo was all over it. You need to remind yourself that you are not the 'shitty paying jobs' that are out there, you're better than that and when you believe it, so will they.
Or since you love writing and Steemit so much, maybe you should go all in.
