I've been in this position for the last 3 weeks or so, for two reasons. Reason #1 is that I got engaged to my lovely girlfriend, and the excitement of her moving in combined with starting to plan the wedding has taken up all our time.
Reason #2 is that i'm starting to second-guess the songs. I like them, but I feel that I can do better. At what point do you show your cards? I do love these songs, but I feel that they're not quite 100%. Do I hold off and rework, possibly ad infinitum? Or do I just take the leap and release as they are?
