I have pretty short hair. I cut it all of because I was tired of being told I looked like I was 13-15 when I'm really 19, and I thought a shorter hairstyle would make me look older.
It did, and I liked the cut, but now I'm ready for my long hair again, so I'm growing it out.

Plus all the guys who've seen me or pictures of me with long hair tell me I look better with long hair and that I should let it grow.
