You say the word social and you'll come up with different ideas. You are social. You involve yourself in different activities that people enjoy. Social organizations are prevailing. In fact, lots of people have benefitted in the efforts of those who genuinely want to help. In addition, a part of this is your ability to interact with other people. It's not just about extending your hand to those in need but also to acknowledge that we are all interconnected by an invisible bond.
Instead of wanting how to do social; better learn how to be social. Focus on how to be a good influence. Choose helping instead of burdening people. Look around you and see that there are lots of things to do.
