Worry:

Taking energy from today,
To think about tomorrow,
A sort of twisted way to pray,
For calamity and sorrow.

Hope:

Taking energy from today,
Wishing for better tomorrow,
A slightly more positive way,
But still energy you borrow.

Conclusion:

Hope is worry in sheep’s clothing,
Discontented positive spin,
Forget what tomorrow will bring,
Live fully the day that you’re in!
