When I have something and I really love/appreciate it, I can not help but to share it and give it away.
POINT is...
If we have it we want to share it.
If we do not have it no way can we help/share/give anything to anyone.
Jesus came to bring reason. Think, why am I doing this, think, reason, don't just follow.
Buddha, saw outside his castle walls and thought, goodness how can I help these people?
People, who see a need will help from the desire to help, not for what they will get in return, not for all the virgins in heaven, not for any reason other then to be of service.
Think...reason....

"We tend to forget that happiness doesn't come as a result of getting something we don't have, but rather of recognizing and appreciating what we do have."

If you want happiness for an hour — take a nap.
If you want happiness for a day — go fishing.
If you want happiness for a year — inherit a fortune.
If you want happiness for a lifetime — help someone else.

Happiness is like a kiss. You must share it to enjoy it.
