I agree. While I can have empathy for OP's feelings, when he says he's changing the world with upverter, you can't help but think he's being delusional. It's just a site that shares your mechanical drawings.. let's not get ahead of ourselves here.

Your own happiness comes first, not some imaginary customers who want to use your product to make themselves more money, or inject themselves with more dopamine... they don't care about your well-being at all.
