[something something it wasn’t like this under the XYZ administration]
I've heard that shaving it is actually a lot of work, so investing in some good clippers and buzzing is likely easier.
Works best when you're not going for some fancy look though and just want something clean and simple.
I also do my kids hair, though the girls keep theirs long so thats just a matter of brushing it real neat and make a straight edge. The boy is too small to take to a hairdresser anyway.
I also do my wife's hair. She is the only one where some thought and planning is required. I'm amazed that she lets me.
I start by use a number 5 guard (can't remember the actual cutting depth measurement) and run it over my entire head for a base level. Then I use progressively shorter guards on the sides and back, usually down to a 2. I will then also use the 2 to clean up around my temples and hairline to get a nice clean look.
As for the back, just gotta get used to finding a comfortable grip with your bent behind your head and use your other hand to touch the guard and your head at the same time as you go to get a feel for where it is and how it's oriented. A hand mirror is useful too as you can use your free hand to hold it behind you and see what you're doing by looking at it in your bathroom mirror.
Unless you're really skilled (I'm not), just go for a very short, simple cut. If you have someone who lives with you who can help you use a trimmer on your hairline on your neck, that's very helpful. Frankly I can't tell the difference between cutting my own hair and when I would pay $30 for the same cut.

(Except mine was way cheaper, Ikea probably) oposite my main bathroom mirror. So facing the swing arm mirror I can see the back of my head and since it's through two mirrors the hand actually moves like you'd expect when you look at it.
The secret to cutting your own hair is learning to quit while you're behind.
There are easier ways of getting a cheap hair cut. :) Welcome back!
