The galleries are full of critics. They play no ball, they fight no fights. 


They make no mistakes because they attempt nothing. Down in the 


arena 


are the doers. They make mistakes because they try many things. The 


man who makes no mistakes lacks boldness and the spirit of 


adventure. He


 is the one who never tries anything. His is the brake on the wheel of 


progress. And yet it cannot be truly said he makes no mistakes, 


because his


 biggest mistake is the very fact that he tries nothing, does nothing, 


except criticize those who do things.
