One piece of wisdom for any messenger spreading visionary ideas in the world. Be careful to protect yourself from the opinions of all but a few carefully selected, trustworthy mentors who are on their own visionary journeys. And remember that the feedback you’ll get from others, none of it is personal. When you’re brave enough to get into the arena, you’re going to have critics. But remember, they’re not criticizing you. They’re just reacting to what they don’t like about themselves in the mirror that you hold up. The same is true for those who are cheering you on. What you’re reflecting back in the mirror you hold up shows them the best part of themselves. But none of it is about you. It’s all projection. If you personalize the criticism, you won’t get far on your mission. And if you internalize the praise, you’ll become a diva with a swollen head. As Theodore Roosevelt expressed best, “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.” Lots of people will try to criticize you from the stands of the ordinary world, when you’re out there in the arena, stepping bravely onto the path of your hero’s journey. If someone doesn’t have the courage to get in the arena with you, the advice can’t be trusted.
