Just to clarify, this is not solely about length

I just want to clarify that I am not hung up on getting long hair; I've always had short hair and I actually like it better. The only reason I've named such specific lengths is because I want to see the progress that my hair has made. I'm also curious to see exactly how long my hair can grow. I have no burning desire to have hair down to my ankles, I'm just testing the waters ;)
