are you empty or full

I hold it in my hand
it contains thoughts
some call it empty
others not
our outlook in life
revolves around a cup
some take in
some clean up the slop
yours might be empty
or at the top
perception in life
is what it's about
and so it is
my personal wishing well
my cup runith over
and it casts a spell
to those who see
perception is key
if it runs dry
I'll fill it up
optimism is my liquid
so give me a squeeze
I wash away all negativity
don't stand too close
your feet will get soaked
my cup runith over
