Everyday :-(

I really have no idea what I want in life. I am still young. I live life as mundane as just passing every another day. Each day is such a similarly normal everyday, not a happy day, occasionally a sad one.

Why am I not so happy everyday? Because there's something wrong with me?

I feel I am becoming more of a grumpy person, so I went out to have fun. Don't know why I am still feeling the same after that. How can I be a happier person?
