How many people do you see in the professional sector that aren't well groomed and for that matter even have facial hair? Rolling out of bed, throwing on some wrinkled clothes works in college. It doesn't work in the real world. I did it too, but as soon as it came time for a real job the hair got cut and the beard went away.
Keeping the hair short makes it low maint. in my mind. Roll out of bed, take a quick shower and shave, throw a little gel in it or just make sure it isn't sticking up everywhere (mine usually is so the gel keeps it from having a mind of its own) and off you go.
Correct me if I'm wrong, but JetBlue allows goatees.
