Should the guy always make the first move?

I'm a very straight forward go getter type of girl without being too pushy and I've liked this guy for about 2 months. I think he's somewhat into me. He looks my way and he's always around even though we don't have any mutual friends. So since I'm such an aggressive (impatient) person, I usually just tell the guy that I like him, but my friends and my mom tell me every time that I should wait for the guy to make the first move. I'm trying to wait for him to make the move, but I'm dying here! Should I just tell him I like him or should he make the first move?
