why is it that we always think our perspective is correct?  

or at least 'righter' than the next guy's?  is that just human nature?  

how can i have an appropriate amount of confidence in my ability to judge and think and decide but still be open to what i don't know? 

(which is considerable, i must say)

how can i be certain without being arrogant?

i think life is full of these juxtapositions...
