This has been a problem for me. Wondering how everybody else goes about it. Well im not in a band right now which could be part of it but when i practice by myself sometimes i try to learn songs but it seems to be kind of a waste cuz ill learn it but then a little while later if i try to play it especially if theres lots of variations ill start fumbling or forget the next part and just stop playing and i feel like i suck then, like if i try to just play bass in front of someone. I think its also like when im in front of ppl like i can play it in my room but if im playing the bass ill mess up cuz i forget the next variation. Should I not worry about learning songs till im actually in a band? Maybe i should just work on other stuff like my ear and groove or something or just practicing playing thro chord changes and what not?
