So true! I’ll be the first to tell you the _vast_ majority of those ideas were objectively terrible but every single one of them taught me _something_.
I've got a giant list of ideas (99.9% horrible) i've kept over the years. they always seem exciting when I'm writing them down ..but a week later they seem laughable. I always find myself thinking, despite realizing the idea is horrible - that I should have created a 2 or 3 page website as a business-like pre-mvp on the concept while I was still excited about it.
