Hammer or Hatchet?

It's tough changing
and becoming the person
you want to be,
you always wished to be.

hammer or hatchet,
both hurt
when they come down 
on your knuckles. 

then my daughter reads my mind
and says something
that I always say to her:
"Good thing you're tough."

I am not tough,
but it is amazing
what being reliable 
does for your confidence.
