I like this quote from pg:

>In a way this is virtuous, because I think startups are a good thing. But really what motivates us is the completely amoral desire that would motivate any hacker who looked at some complex device and realized that with a tiny tweak he could make it run more efficiently. In this case, the device is the world's economy, which fortunately happens to be open source.

After a while you learn to ignore criticism. I'm not really interested in what people have to say who would never become users anyway. They're simply not the demographic. It's all noise, and when I was younger and more impressionable it caused serious self-doubt. But when I demo something and I see the eyes light up, and then they say "well, what about this?", that's pure gold.

Valid and useful criticism is rare.

Critics providing other sorts of criticisms fall into a bimodal distribution. There are those who criticize because your proposal seems risky and they don't want to see you fail, and then there are those who criticize because they don't want to see you succeed.
