I feel discouraged when i play guitar
I have played guitar for about 5 years. I own an acoustic and electric guitar, nothing terribly fancy. I've always enjoyed learning new songs that I like, and can sometimes get fairly good at them. However, I've never really played for more than about 10 to 30 minutes per day, sometimes not at all. Until recently I've been content with just learning to play other songs but lately I've felt this overwhelming urge to create my own music. However, whenever I try to come up with even a simple progression I am paranoid that it sounds too much like another song. I feel like everything I manage to come up with is heavily derivative of whatever I've been listening to lately. As a result I feel frustrated and stifled, and whenever I pick up my guitar I feel tired and discouraged after no more than a few minutes. It has really worn me out. Is this normal?
