Congratulations on your very wise decision. Keep shaving it every day. Stick it out. You won't be disappointed. One of my only regrets in life is not doing it 10 years earlier.
You are going to need to maintain it daily because unlike a normal haircut a shaved head starts to look bad in just 2 or 3 days. Your barber won't be practical anymore. Get a buzzer or a razor, and clean it up daily.
If you haven't started an exercise and fitness program yet, now would be a great time to do so.
