If all you want to hear is how awesome it is, then go show it to your mum. I'm sure she'll tell you how special you are and that you can do no wrong.
Sounds like a strawman to me. Who here has said anything about wanting nothing but positivity, or to be told how awesome they are? Even negativity can be combined with encouragement and support. And it doesn't really cost anymore to do that.
A. "Your idea is pretty bad. You suck. Kill yourself."
B. "Your idea is pretty bad; have you considered XXX? At any rate, best of luck to you!"
OK, to be fair, (B) cost a few more characters of typing for the pedants in the audience. But there's no significant extra cost involved with throwing a little encouragement and support someone's way.
