I think that working outside comfort zone is not necessarily doing the stuff you don't like. You should do the stuff you like and the stuff you're good at - going out of the comfort zone is trying to break working routine and finding new solutions for old problems, it's, in fact, changing the state of mind and constantly learing new things about stuff you like and stuff you're good at.
Of course, there's still need for objective look and understanding of what should be done first. I guess, balanced team of technical and non-technical cofounders should be the way to have it.
