What should I know?

Hey everybody. I'm brand new to CA and cigars themselves. My friend and I were in a tobacco store. We were just picking up some cigarettes but I decided to check out the humidor. I walked in, and it had a very nice aroma. All the different types was amazing. I wanted to try them all, but I only had a few bucks on me, so I bought a Hookah Tahitian Vanilla by Drew Estate. I really didn't know who he was, but it looked pretty fancy so I bought it. But I haven't smoked it yet. I really don't know what to look for in a good cigar. You guys want to fill me in?

Until now, the only cigars I have ever smoked were the cheap ones at the gas station. So again I know nothing about cigars, but would like to learn.
