Passive.. Active

Passive? Active?
I would describe myself as a rather passive person..
Even though I already said to myself that I must change my silent habit, I still cannot overcome it.. Even the lecturer is being rather.. I don't want to say it.. It's just my own impression..
Maybe I should look more enthusiastic.. ARGH.. My communication is getting worse and worse..
I must overcome my timid character starting now, or else I'll be drowned in a pool of people..
Haha.. For my b'day wish, perhaps I should wish that I want to become an outspoken n spontaneous person.. That should do it.. Express myself more in front of people, and not to confide everything in my mind...
