if not now when?

today is the day
so no matter what obstacles appear
and even if around every corner
the sand-filled sock awaits us all
you still have to give it your all
you still have to
pump yourself up
gather all your forces
give it your all
make it work
think that it WILL work
put the sack on your back
and go up the hill singing merrily goddammit
and put your best freakin' foot forward
because what the hell else do you have
but your belief
that things are going to work out for the best ?
what else?
