Only interact with those in the ring
When you get advice or criticism from someone who isn't actively involved in that subject, ignore them.
The social media critic who only judges others.
The parent who judges without full understand.
The person who thinks they know best but hasn't done a thing in their life.
If you're ever faced with this type of feedback, which you will be if you're making anything in this world, remember these words from Theodore Roosevelt:
“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.”
