overwhelmed with social media

I'm a mass communications major and I can't keep up with all of these social media networks. How does the average American not feel overwhelmed? I really want to give it all up but I can't because it's supposed to be my job! So, I shall continue to try to master the art of Twitter, Pinterest, Google+, etc. and ways in which it can enhance and promote businesses and organizations. But after I'm done watching Gossip Girl and finishing the conclusions section of the Master's Project. Soooo ready to be done with this and graduate!
