Q: I have lots of things to record but no idea how to start recording them.. it's an bottomless hole of not having enough time, not knowing the song well enough, not having enough technical ability to pull off a good take, laziness, or being afraid someone can hear me
A: this won't solve all you problems, but it will solve some of them: try doing much much much much much much shorter songs, to start out with. this will allow you to start finding solutions to all those problems, in a very bite size and manageable way
