There is a lot of advice flying around here. Some of it is great. However, I think we need to know a little bit more about you before we can really help. Look at it this way guys....
Scenario 1
BassMoley is 13 years old, lives in a field outside of Nowhere Nebraska (population 12 with no other musicians within driving distance) with his uncle Zeb, has no money, no car, and no patience for anything (much less bass), and loves very technical death metal.
Scenario 2
BassMoley is 30 years old and single, lives in the heart of NYC, does well financially, took up bass on the advice of his therapist to relax, and loves punk rock and three chord classic rock songs.
I would advise Scenario 1 to quit and take up sling shot shooting. I would advise Scenario 2 to relax, have some fun, get a private teacher, and join a band of equally terrible musicians so they can all earn together.
My advice for those two situations is completely different.
