I've developed a few ideas that I would love to work on, but I'm extremely pessimistic about business ventures. If anything remotely similar to my idea exists, I assume that they've considered my idea and there's something I'm missing. Like there's some reason it wouldn't work the way I'm imagining, and I'd fail. So yeah, I tend to quit unless the idea is super unique.
