I don't think there's anything wrong with being earnest. Some people will see it as a weakness. Some people will like you for it. I vote that you keep that side of yourself. Put yourself out there, like you did here. Some people will make fun of you, but someone else will give you work, or a piece of good advice, or a little bit of encouragement, and that's what counts.
