What can *I* do?!

I've asked that of myself for the bazzilionth time. I can vote, I answer myself for the bazzilionth time.Then I try to think "out of the (draw a box with my two forefingers, starting at the top middle and ending at the bottom middle)"-talk to my family and friends-get my opinion out there using a medium perfect for engaging complete strangers and spreading virus-like opportunities (all the while gathering new opinions, potent information and ideas)-(and the hardest for me) don't clam up when around people I normally don't talk politics with. I'm referring to person-to-person communication, which takes confidence in yourself and in the topic. Said confidence usually occurs when discussing movies, books, art, design, cars, astronomy, science, yadda yadda... but is seriously lacking in politics, html, investing money...It's all about taking chances, right?
