Been "struggling" with this for years. It seems working on one is to the neglect and detriment of the other. They both require a lot of attention to do well. I don't mean a specific song, but rather my identity as a musician in general. I enjoy singing and playing chords. I'm a better lead player than singer though. I'm still naive enough to think I can get good at one or the other. Overall, I think working on my playing will yield a higher musical return, since I could theoretically become a very good guitarist, given my current level and experience. I just find singing to be more rewarding in the short term, and in some ways more useful. For instance, grabbing my acoustic and playing something, a voice is an important element. When my voice is in shape, it sounds ok to me. Just ok. I want to do it all. Just not enough time though. I know you can't answer this for me. Just wondering if anyone else has the same dilemma.
