The most beautiful thing we can give a person is our time, our attention. And even more if everything is disinterested, we could remember that phrase "the good deed of the day". I enjoy helping many people constantly on the street, some favor, some direction, or whatever nonsense they need, then the satisfaction that I have left is incredible. The best part of that is that you will have your own benefits, maybe in the future you will be in the same situation and another person will give you your time or your attention.

Life is about connecting with other people, socializing with our peers and thus we will be much happier, I am sure. We will become better people. Not always in our life will focus on "what we will receive in return."
