I have a list of projects that I would love to do. The last time I started a project because *I* wanted to make something (ie no-one was pregnant, getting married, etc) I laid out the top choice patterns and went through my stash - I then picked the one that had the best options already in my stash!!
That quilt is now on a back burner while I finish a "getting married" quilt. This seems to happen more often than not.
