Ok, in need of legit advice now. I was told to act more "aggressive." I guess I do have a more reserved personality, I usually prefer to think before I say things, and always want to make sure they come out right. I am definitely not the loudest person in class. I actually sleep through most of my classes (this is part of the reason I don't raise my hand in class). When professors ask if there are any questions, I could rarely come up with a very good and difficult question, because in my opinion, if I ask something easy or something I could figure out on my own, it is simply not worth wasting class time. So I don't want to just ask questions for the sake of participating.
Also, I prefer to listen to others who are more experienced than me because I like to learn from them, as they clearly had more experience in the workplace and finance, and have much more to add than me. So that's another reason why I sort of take the sidelines.
So what exactly does being more "aggressive" mean? Does it mean asking more questions or being more vocal? Did anyone have this experience also and can give advice?
Side note: among my friends, it is actually the opposite for some reason. It is only in work place and classroom that I come off as "reserved."
