A Proverb

A proverb of my own:

Don't sell your soul to the future.
You will probably lose interest.

Don't give your heart to the past.
You will need it today.

Don't waste your strength on just anything,
but give your strength to something worthwhile.

Don't lose your mind over minor challenges,
but let your mind be challenged by worthy things.

Inspired by Philippians 4:8;
"...whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things."
