I had a product idea, and Amin happened to find a product that sounded exactly like my product idea. So, I was like, aw dag, they did it first, and I instantly put it aside.
I happened to get curious again, and I just tried it now, and it's not what I was thinking at all. They are thinking of the same problem as me but are not coming anywhere close to solving it. Still, part of the experience is very similar to what I'd have done, and it is lacking. So, it was helpful to get a glimpse of how my approach would have problems, too.
