Said many times in most cultures, this quotation from Teddy Roosevelt phrases the sentiment as good as any I know of:
“It is not the critic who 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 strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”
— Theodore Roosevelt

I am the offspring of two doers. I was raised their way. It is not something I chose, nor something I can turn off. It just IS. The snipers are out there. Oh well. If they are annoying enough, I shoot back.
