You have to at least try...

Don Juan in Carlos Castaneda's A Separate Reality - 
The difference between a warrior and an ordinary man is that a warrior sees everything as a challenge, while an ordinary man sees everything as either a blessing or a curse.

Teddy Roosevelt -
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 and comes up short again and again, 
because there is no effort 
without error or shortcoming . . . 
who knows the 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 know neither victory 
nor defeat.
