i had long hair beyond shoulder length once. one day on a whim i cut it into medium-longish-spikes-on-all-sides length. i was surpised like FUCK it looked awesome!
then it grew out again after some months. twas alright but then one day on a whim i have it straightened. i was like HOLY SHIT this is great!
today i have slicked back superman-length hair and it looks badass especially with sunglasses.
moral of the story: same hairstyle all the fucking time = boring. change = good.
So do I. Its a lot longer in the back than in the front.
