This is pretty spot on - I hate to be the one arguing for "less thought" on a subject/concept etc. But I've definitely gone too far too often .. so I try to stop earlier more often now - for feedback (and implementation as you suggest) knowing I can always go deeper. I find that asking one's self this question is helpful : "Are the barriers to believe for concept ________ technical or something else?" If the answer is that there aren't deep technical barriers - its a good time to stop and start collecting feedback.
