“It is not the critic that counts, not the man who points out how the strong man stumbles or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood. Who at best knows in the end the triumph of high achievement, and who at the worst, if he fails, fails while daring greatly.” Theodore Roosevelt
Don't take to heart criticism from strangers online. They know nothing about you, care nothing for your feelings, and have no impact on your business whatsoever--unless you let them. When you stew over a comment, it gives them power.
Whatever you are putting out there into the universe is better than what that person put out there that day.
You put positivity, creativity, joy and enthusiasm online. She put negativity, unkindness and clamor.
Who should we feel sorry for? Her. Not you.
You're doing great, and you're stronger than one nasty stranger's burp-up on the internet.
