Exactly, what do you as of right now, this moment of your life you hobby/career do feel like you've "mastered" because
1.)you never really master anything in art there is always much more to learn (don't mean this in a bad way, trying to motivate you)
How much work have you put in theory & fundamentals?
Look back at your work, listen to it, song structure wise harmony wise, melody wise. Do you think you put in 100%? Ddid you rush your tracks just to finish them?
A lot of projects, I've read from guys like madeon and stuff say they work on 1 track example Technicolor I'll post the link at the bottom tho I'm sure you've already heard it took him 7 months I believe he said. He would be on and off it changed various times

Madeon quote follows
I've been in the studio for three months and written a bunch of songs and thought, "You know what? Not good enough." I thought I'd take three months off from touring - which is a big deal as touring is profitable - but I need some level of productivity. So I went to the studio to create. But I wasn't [thinking], "I need five new singles for the next 12 months." It was rather, "Let's study movie scores. Let's see what that is about." I'm glad I have this knowledge as now I have something else I can do. You can either cultivate spontaneity or you can be exhaustive in your knowledge and capacity. I'm more towards the latter. You know, my music sounds happy, but it's a painful process and I take it quite seriously. I do realise that if I keep on with this attitude forever - of scrapping songs and taking six months to finish a record - I'll pretty much have an album in 2035.
Here's a thread started by madeon showing off his struggle & tips
https://www.reddit.com/r/edmproduction/comments/186kli/im_madeon_lets_talk_production/You're thinking of this (the whole music thing as money) it shouldn't be about money while everyone here wants that, priority number one should be about what it started with
Music and should in with music
There's a quote in Kill The Noises song, I'll link the bottom with the song the quote is in the song & hope it makes you not give up I'll quote it as well
"You got to reevaluate you perspective & you priorities, because, you started doing this because it was fucking fun, it has to be fun, otherwise, you're just torturing yourself you know, you're just stuck inside you own fucking head"
https://soundcloud.com/killthenoise/all-in-my-head-feat-awolnationI find inspiration in music, anime, other peoples work, score, films
Music isn't just about understanding music in an album or ep, it's about understanding sound not just in music, but in film, IRL event's, film piece together how a song in a film or in my case anime makes you come to tears. Evaluate it as sound, a person or being that provides support in an intangible way it moves everyone because someone took the time & learn to struggle to provide that feeling in you.
But as a guy who started in high school now been producing for 2 and a half years, 20, still a lot to learn, I have dropped out of college for this so I can somewhat understand what you're going through but i'm having fun with this, I love this in the end, I'd rather die doing what I love than living & working in a office. The world needs more creative people and less men with black and white shirts and black neck chokers around their necks who kill imagination. That's all I can say, hope it helped
Btw this was madeon now he was 10 I think, but still it took I'm 10 years to get where he is now. link in the bottom
