Many people in this USA tend to have eyes bigger than their stomachs. Try ordering less next time you go out to eat. Or if there are left overs, ask for a To-Go Bag and then give it to the homeless person begging for change at the Freeway Exit.
When there is a sale on soups (with a pop-top) buy a few cans, keep them in your car and give it to the next homeless person who reaches out to you.
If you work downtown, buy an extra cup of coffee and hand it to the fellow on the corner.
That extra few dollars you spend will come back to you multi-fold in good Karma.
