Whats the point

Whats the point
in doing something half hearted,
to do something
but not give your absoulute best,
to write with out paper
or to sing without words,
give your all in everything you do
and don't ever quit,
don't train till your fit
train till you can't train anymore,
don't run till your tired
run till your legs fall off,
don't finish before you start
and do everything with all your heart.
