Any Barbers on here?

Hey guys, my Grandfather owns a Barbershop in Anacortes Washington called: The Clipper. Grandpa offered to help me pay to go to a good Barber School and then come up and learn from him, with the hope that when he retires in a few years, I can take over the business. While this is an awesome opportunity, I have no idea what being a barber is really like. Any barbers out there who could give me a decent idea of how it is?
