I just finished reading this post about how ideas do not matter. The post is wrong, ideas do matter. The point the author is trying to make is that trying to hide your idea from others isn’t going to help much, which is probably true.
Ideas do matter though, you can’t change that. A business based on customers paying to have poo flinged at their faces really isn’t going to fly. I just think the author is kind of jaded about it. Ya, don’t worry about people taking your idea so much, but do worry a bit about having a not-crappy idea. However, if your idea for a business is to fling poo at your customers, obviously your idea sucks.
In the end if you can come up with something you can feel good about working on, that’s the real winner here. The inspiration that Eric talks about is very important, so definitely figure that out as well. It’s about the whole package, not just bits and pieces of it. If you decide you want to go pitch your idea, keep in mind that 20 others have probably pitched the same or a very similar idea. But stick with it if your idea is important to you, and you know you can make it work. Get inspired, get others inspired, and get to it.
