If you're doing anything interesting in the world, you are going to have critics. You can't stop it. Move forward. It's not worth losing any sleep over.

If you never want to be criticized, for goodness' sake don't do anything new.

I think we've seen it all. The e-commerce store is the interesting one.

No one has ever achieved anything significant without a chorus of critics standing on the sidelines explaining why it can't be done.

To turn really interesting ideas and fledgling technologies into a company that can continue to innovate for years, it requires a lot of disciplines.

Nothing is easier or more pathetic than being a critic. Because they're people that can't get the job done. But the future belongs to the dreamers, not to the critics. The future belongs to the people who follow their heart no matter what the critics say.
