Why is it that we ignore the most simplest concepts? Do Good. It's simply the right thing to do.
I've learned through great advice and later through experience that each of us has either time (volunteer), talent (your skillz) or treasure ($$$) to contribute to the world. If you don't have money to give- that's ok! You have plenty of other gifts to share with the world. You just have to be open enough to give them.
Check these folks out at Catchafire. They are a perfect example of what happens when someone comes up with a creative way to share their gifts. Find your venue or your cause and watch what happens.
The happier you are, the more you give. The more you give, the happier you are. And studies show that happy people who give, are more successful and less stressed.
