Serious advice: Learn to live with it.
It's so much easier to say "oh yes, sounds like a nice idea" than to actually sit down and try things out. How often do you act like this on your own?
The most difficult things to deal with as a founder / creator IMHO is not to deal with criticism, but to deal with indifference. People just don't care. You can't change this.
Hence, learn to accept it.
