Much easier if you're happy with a cut that simply involves running clippers over your entire head. 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.
