I can’t take credit for this wonderfully grim phrase. I can’t even remember where I first heard it but it stuck with me and that’s what counts. Our babies are the ideas we are attached to that prevent us from shifting gears and letting our concepts evolve.
Babies usually contain the seed of a good idea, which makes them hard to release. They consume your time and distract you from alternatives. They are the ideas that no ones else seems to 'get'. They are the amazing ideas that you can't seem to finish. They are the things you defend emotionally but can't describe their quantitative value.
Recognize when you're defending a time sink. If you feel overly defensive when an idea is criticized there's a good chance it's one of your babies. Step back and shift gears.
