The answer is kind of in the original question.
"Should I listen to some bass solos?" Yeah.
But deeper than that,
Have you not listened to many bass solos?
If not, then why do you want to do it?
"Having something to say" is right! I think it takes a mature person to figure this out, regardless of age. Where I'm at, 95% of the stuff I play kind of sounds like stuff other people have said or stuff that is obviously the result of the constraints of the instrument, its geometry, and my technique/vocabulary. 5% is pretty cool and you might not get it anywhere else. I think this is a consideration for someone that wants to get out of the bedroom w/ their soloing.
