Think Fast

I can not think as fast as you
I'm not a genius either,
I work hard to understand
and you go ten times farther.
I do the problems at my pace
and you go times faster
And I'm not doing easy stuff! 
But in calc, you are the master. 
I can not comprehend these numbers
in seconds 22-
And yet you understand these things
while you tie your shoe.
Maybe I should not compare,
we all have different features
I really shouldn't be discouraged...
except that-  I'm your teacher
