Whenever you create something new there'll be millions of people who won't care about it at all.
Tens of thousands of people who could probably have done a way better job than you did (but they didn't).
Hundreds of people who are going to say that they could have done it better, faster or cheaper than you.
And then there'll be a tiny group of people that will really appreciate what you do.
And those are the ones that really matter.
Do it for them.
And no one else...
