I buzz mine too, been doing it since 1995. Your current style looks like the flat top. I went from parted in middle, even side part and business look to flat top and eventually the buzz with varying lengths, to now, where I don't even use the clip on attachments to delineate length anymore. Clippers paid for themselves after the 3rd cutting. Anyway, from the avatar, the head shape you have looks like a natural for the buzz cut. Even your squarer and pronounced jaw line is natural for the buzz cut.
At first others might think you've lost your marbles, but the maintenance on the buzz is minimal and you're going to love that. My buzz cut when one rubs against the grain of the hair is still relatively soft and even softer when rubbed with the flow of my natural hair. Most women that rub my head are surprised it's as soft as it is. It depends on your hair type, but I have to re-buzz every couple of weeks at best and once a week when I really want to keep everything high and tight. Anyway, it's 10-15 minutes total time to cut it it and you'll want to make a couple passes to ensure you got all of it. hand held mirror looking into another mirror and you'll see you got it all or what needs another swipe/pass over with the clippers.
Shampoo, you won't need that, but can still use it just the same. I usually soap my head and rinse. The economics of a buzz are awesome. Shaving, that would be more effort than I'd want to do. Be prepared to wear a hat even more so though, sun burn is not fun. But you won't ever blow dry, need mousse or anything else. Throw that brush and comb out. Shower, towel it dry and you're dressed and out the door. And on a hot day, It's like rinsing off your skin and you can be dry in the time it takes to pat your head with the towel. believe it or not, some women prefer the buzz.
After buzzing my hair, I was instantly referred to as a Jim Cantore look-alike (the guy that covers hurricanes on the weather channel). For the record I beat him to the hair style so it wasn't like I was copying him.

BTW, buzzing without attachments, don't worry about hair around your ears, just fold your ear over and get all of it leveled off.
