Adeo Ressi says stop protecting your mediocre startup idea. No one will steal it. If your idea impresses someone enough to steal, recruit them as a co-founder instead. The real work is killing bad ideas fast, not guarding them.

So the first thing that I have to convey to you, and this is a common problem among moronic chimp entrepreneurs, is that they have this thought that someone's going to steal their idea. No one is going to steal your stuff. Stupid idea, right? And if you were able to articulate your idea in such a way that someone was so impressed that they were actually interested in stealing your stupid fucking idea, what would that mean? You have a fucking co-founder, right? Which is like, ah, I actually convinced someone that my idea is not that dumbass, maybe he'll come work with me on it. Or she'll come work with me on it. But it's, you really, I guarantee you, you should be talking about your idea all the time and soliciting feedback as much as possible. And really do not worry about people stealing it because most of you have pretty shitty ideas anyway. In fact, your job is not to fall deeper in love with your dumb idea. But your job is actually to kill it.
