serious question

It has come to my attention via pictures that were taken this weekend that my hair is getting too long.
As many of you know, I had a mishap a few years ago where I cut my own hair and it made me look like a head of broccoli.
It was while I was writing my thesis for undergrad. Suddenly, in a mad existential fit, I decided not only that I wanted short hair…but that I wanted to do it myself.
My roommate should have been scared. Especially since I recently told her of the long literary history of female protagonists killing themselves after cutting off all of their hair.
Anyway it didn’t take me long to realize that I wasn’t meant for short hair.
I vowed to keep it long forever.
But now my hair is looking nasty.
I want my hair to scream “I am confident and attractive”…
not “i believe in polygamy.”
And right now I look a little too Sister-Wives…if ya know what I mean. (If you don’t know what I mean…you don’t watch enough television and I am judging you on the inside).
So I need everyone’s opinion on how short to cut my hair. Emails with pictures are welcome.
