you have no idea just how happy you are about to be, no more looking for hair to comb, no more bad hair days, you will look about 10 years younger, YES it's going to take time, YES the little rolls on the back of the head are not easy to get too and yes there will be times when it does not "feel" as smooth as you want it BUT it will "look" pretty decent, some areas stay "gritty" while still looking shaved, so don't worry much and welcome to the club
