When is enough enough?

Sometimes, enough is just not enough.
Sometimes, not enough is just enough.
It takes so much to love.
One gives and gives and gives.
Understand and understand and understand.
Going all the way and not expecting anything in return.
But how many Jesus can there be?
How noble can a man get?
How much sacrifice then is enough?
Why do mankind always seem to be not having enough?

Maybe when it is enough, then it is enough.
