what to do with my life

As many of you may know I am going back to school.
it is not ging as well as i had hoped.
somehow all the med classes just
aren;t working out
i am not sure if
nursing is for me
why is it so hard
at my age to know
what is the right thing
for me to do.
i don't expect school to be
easy
but i thought if i
chose the right career
that i would be
more interested in
my studies
i am not
how do i find what is right
for me
