Try not to take it personally.
You poured your heart and soul and sweat into it. It’s something you created and a little part of you is now in it. But nobody seems to really like it.
That’s OK.
This is a great opportunity to figure out why people aren’t using it.
I will bet any amount of money that it has nothing to do with you.
Maybe it does’t really solve the problem. Maybe it solves one problem but introduces another. Maybe it was too hard to understand.
But it’s not you. It almost never is.
