Too quickly, venting can turn into dumping garbage on the people around us.

Following celebrities or people you don't regularly see in person often doesn't add to our happiness. The best use of social media is to deepen existing close relationships or create new ones.

Know that positive change is possible. It might not happen right away, but if you change your broadcast to them, that can have an effect on how they view the world.

My big "double-aha" moment came while anchoring the national news at CBS News. It was at the height of the recession, and on top of the usual negative stories, my newscasts became full of especially heart wrenching stories of people losing their homes, jobs, and retirement savings. Starting the morning off like that could leave even the most optimistic person feeling helpless and hopeless. The lightning bolt came when we changed how we talked about the negative.

Catching up on pictures of your good friend's kids ahead of a visit across the country to see her is a great way to deepen your time together. Following near-strangers can leave us feeling detached and lonely.

We are ALL broadcasters.

Too often we forget how powerful we are as individuals to shape how other people see the world. Each one of us constantly broadcasts to other people - whether consciously or unconsciously - verbally or non-verbally - and those messages influence their brain.
