+1 to the 'get a teacher' backers.
as I said in another recent reply to thread. "If I had it to do over (and I Dont, so..) I would vicariously tell my high school self -now you- to" ...
Do the Grunt work. its worth it.
Learn your Fret board and Maj/Min, Pentatonic and Blues scales.
Spend time learning to read music (at this tender age you don't realize the foundation it can provide for you in the future if you keep at it). if someone calls out a key center you need to know where it is on the bass.
Do some ear training
get yourself a small keyboard. even basic keyboard knowledge (again reading will help with this) has a way of laying out scales that stringed instruments cant replicate. plus you get a bounty of ear training on interval and chord qualities, etc, the like.
and join a jam/garage band and play. playing should be fun, so find fun songs and play them even if its not your primary instrument.
a condensed story;
I had joined a band in High School. I put in a ton of practice time, but I was not 'play out' ready yet. (did not have my own instrument yet, and the one I was borrowing the kid wanted back

) So they had a girl who played bass fill in for that gig. It burned me to my core that I wasn't 'good enough' to play the songs that I had worked so hard to get the chance to play! So, I made a vow that I would never let anyone else get the chance to 'sit in' for me unless I was injured or something along those lines. I saved my cash and bought a Fender P and a small amp so the -no bass thing- was no longer a hindrance either. It was a small event that was a few hours long, but it resonated in my motivational engine. It kinda still does after writing this, lol. but I am glad I had to endure that growth process. I don't think I would be as good as I am now if I wasn't 'benched' that first gig.
hopefully all of that babbling makes some sense. and more importantly helps you (as well as a few others) out.
