Most people like to complain about all the things that are wrong with the world today -- and it's true, there are many things that could be better. But it's also true that everyone can help improve life around them, one small step at a time!
Start today -- pledge to do at least one kind thing for someone each day, one thing that you absolutely are not required to do but do anyways. It doesn't have to be big, or cost any money.
Some simple examples include giving a genuine compliment; holding a door for a stranger; sending a thank-you card and/or a small token of gratitude when someone does you a kindness; offering to walk the dog or baby-sit the child of a busy neighbor; etc.
You'll find that once you get started, you'll find all kinds of little ways to make a daily difference!
