Thrills, fun, and be mostly carefree. I'd have the courage to pursue my dream career choices without the fears of rejection and incompetence getting in my way, as well as the courage to react to things in public other than having that shy and blank look on my face: I'd laugh, I'd smile,...I might even wave at someone and say 'hi'. Be genuinely friendly and happy without hiding anything. It would be nice if those genuine emotions last more than about 3 weeks.
