Caring doesn't have to mean cuddling. It does mean seeing the people around you for what they are and what they need.
You can't fake caring, either you want those around you to succeed as much as you want to yourself or you don't. People who feel cared for, reciprocate. They'll talk to you more easily and listen with much more attention.
Better yet they'll tell you what they really feel and be prepared to offer you a little benefit of the doubt too.
Action step: Ask yourself how can you demonstrate you care? And then do it.
