- stop lusting for gear. It does nothing for you as a musician. It doesn't matter (though most posts in similar forums are about gear lol).
- suffer. Becoming good at something requires suffering. A lot of it. It isn't supposed to be pleasant. Seeking pleasure everywhere (i.e. dopamine shot) is 3 year old mentality. No pain, no gain. If your goal is mastery, you can't do it without suffering. If you don't suffer while practicing, you're doing it wrong and stay in your comfort zone.
- only the most disciplined of us will make it on their own. Most require strong external pressure, such as music school with tight exam schedule and despotic teacher. If you're one of the procrastinating types, you won't make it on your own. Not in a hundred years. That's the purpose of formal music education - to do things in time + achieve measurable progress.
- music is a rat race, where you have to have a killer instinct. You have to have an ambition to be better than your peers. Without that kind of drive, you'll always stay mediocre. That's another reason why formal education is necessary - there you get pitted against others of the same stage. Later you'll be competing with them for jobs, and musicianship is one of those areas where everything is clear about you after 5 minutes of picking your instrument. Uber transparent.
- Bass guitar is a very limited instrument. You have to play DB if you want to be a versatile bassist. Check out any classical concerto for DB with a decent player, and you'll see that all the Wootens and other pop stars pale down in comparison both in terms of sound, virtuosity, content, maturity, thought, complexity, and so on and so forth. That's like cello vs ukulele. Hamburgers vs gourmet. You can debate it to death, but there's no comparison really.
