Keep it until you need to get a real job.
Funny how things like face tatoos, ear lobes you can fit 44's through, and hair styles like mohawks really limit your salary potential.
During my 3 week LOA during my surgery this year, I gave myself a mohawk. I liked it, but back to my real job where I have to be respected, it grew back out in those 3 weeks and I am "normal" again.
