" It's my life, It's now or never ..."

Sometimes the proverbs can be quite misleading:
You can't hit two birds with one stone.
Every stone is meant for one and only one bird.

In any given moment, you have only one responsibility to attend to.
If you fulfill that one task, you've earned the essence of that moment.
And if you don't, be sure that you've lost that moment forever.

And remember:
Life is vigilant and strict.
It'll never let you get away with it.

So, quit being clever and play by the rules.
You have one stone, one bird, one chance.
Take your best shot.
