If you think back on your life, you will see how even the smallest things have affected you. Most of all you remember the people who have made a difference. Sometimes the biggest influence might be somebody who doesn’t remember you or doesn’t even know you exist, but without that person, you would not be who or where you are today.
Maybe you have made a difference in someones life, a big difference. And you don't even know it. I like to think I have. It doesn't have to be a big thing you had to go out of your way to do. Maybe it's a smile given to a person when nobody but they knew they really needed one. Maybe it's the quick little phone call to a friend at just the right moment. Maybe it's just the calm way you react to a delay in the checkout line at the grocery store. There's really no telling what could make a positive difference in someones life.
It's so trite to say and we've all heard it so many times, but it doesn't hurt to pay it forward; to live each day like it's your last chance to be a good example. It's a lot harder to do than it sounds, but really, what harm would it do to try?
