There is only one way to develop your character of kindness—practice! If you can show kindness to people every day, you’ll form the habit of generosity. I know because I’ve done it. It’s not as easy as it sounds.

Here are the rules for our 21 Day Kindness Challenge:

1. The recipient must not be a family member or friend.
2. You must do it for 21 consecutive days.
3. You must start over if you miss a day.
4. Try different things every day, rather than simply doing the same thing day after day.
5. If you do more than one kind act on a particular day, that’s great—but you can’t carry it over to the following day.
