There are lots of variables with this, also who do you compare yourself to?
I did a 3 year music degree course, I think there were 12 bassists in total in my year. I wasn’t the worst of them, but I most definitely wasn’t near the best of that 12. The difference between the top and the bottom was scary.
We all had different abilities, and strengths and weaknesses. So I may not have been as technically good as some, but my sight-reading or harmony knowledge may have been better. I ended up with a 1st, but that was thanks to one particular module that I excelled in, which actually wasn’t actually bass playing, though it was a solo bass thing.
End of the day, if you enjoy what you do, and you’re not being let down by your ability that’s all really matters.
