Have you ever committed an act of kindness for someone for no other reason than to just to see the smile on their face? I do it a lot. I'm a sucker for smiles. It makes my day.
Sadly, there are some cynics around who say things like, "That was an awful lot of time/energy/money/effort you spent on so-and-so, would they have done the same for you??" My answer is often, "Yes, I guess it was, and I don't know; it doesn't really matter."
Kindness knows no conditions. Acting from the heart and expecting nothing in return is what we should all strive for daily. I am blessed to have people in my life who know this, and I am blessed to be able to give from my heart with no expectations.
Sometimes you have to stop & remember the good things.
