Is it normal to be obsessed with your hair length?

I understand that you ethnic background and things have to do with skin tone, accents,hair, etc. Well, is there anyway or anything you can use to grow your length to be very long (down the back long). I'm okay with the length now but it drives me crazy to see others with the same ethnic background with a better hair texture or length.. I just want to know if you can suggest anything I can use to make my hair longer and more healthier :)
