I know a lot of people say this but I really believe my fingers are not helping me learn guitar. I am doing the course and I can do all major and minor open chords. However, the points of my fingers have a small "puffy" tip on each of them that makes things like an F chord or the harder version of the g chord almost impossible to do (g chord is actually impossible).

Am I being paranoid and I should still persevere? Is there anything I can do to help myself? Should I switch to play the bass
