Here’s one of my favourite pieces of writing from an unknown author:
This is the beginning of a new day.
I have been given this day to use as I will.
I can waste it or use it for good.
What I do today is important, because
I am exchanging a day of my life for it.
When tomorrow comes,
this day will be gone forever,
leaving in its place something
that I have traded for it.
I want it to be gain, not loss;
good not evil; success not failure;
in order that I shall not regret
the price I paid for it.
