To Dare Greatly and Fail

I'm a fan of Brene Brown and her popularization of Teddy Roosevelt's 1923 Speech, where he captures the idea of daring greatly..
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.

Brene Brown wrote a book and arguably started a movement about this, and there's a specific idea in here I really admire: 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..and who at the worst, if he fails, at least fails while daring greatly.  To put yourself out there, and try knowing you may well fail - that's a romantic concept I appreciate - it's the seeds of greatness.  I grew up on the philosophy of Yoda - "There is no try, there is only do, or do not" and I think the little green guy was wrong here actually.  You have to try, and take the leap sometimes. At worst you fail, but then the very act of trying was still worth doing, because it's important to understand enough about yourself that you're willing to fail - and have tried nonetheless.
