You still can do anything

He said: when
I was a child I
thought I could
do anything
imaginable

Now, though,
I’m an adult
and I feel as
though I am
walled in by
heavy doubts

He paused.
But no one
can keep me

from eating
ice cream for
dinner

or flying on
planes if I
want to

or staying
up all night

So what is it
that I think 
I can’t do now?
