So, I used to play bass guitar with a few bands around Nottingham, back in the '90s. We mostly played our own stuff and I just made up basslines that fit (or followed suggestions from our guitarist).
I'd never had a lesson and could only read music / TAB very slowly. None of that mattered, though I knew my technique was poor (I never used my pinky, for instance).
I then developed a weird immune condition called pressure urticaria and gave up the bass for 10 years.
My condition seems to be stable so I'm picking my bass up again, but this time I'm taking some lessons (I may even do some exams!) and shall try to learn to play 'properly'.
whilst still having fun, of course :)
