What's hard is that with an unwilling, tired attitude the scales become drudgery and Shoulds, which sucks the joy out of singing. Exercizes are tedious, but they can still be fun. I don't want to do anything that turns singing into a Should at this point. That's what I'm trying to move away from. But I still need to sing in order to keep singing. It's a conundrum. I find that I do my lip trills while I ride to and from work. That's my compromise.
