Hello Sam,
I'm a little new to the Inspire 1 myself, but I'm willing to help where I can. First, take a deep breath. It's very easy to fly. If you've flown a quad before, the controls are exactly the same. I would highly recommend playing with the go app as much as you can. Try out the flight simulator before you take it for a spin. Before takeoff, do the following.
1. If you are a beginner, turn on beginner mode. This will prevent you from doing anything too advanced and keep you on training wheels (so to speak).
2. If you are not a beginner, and you've flown a quad before, you will be able to fly it very easily.
3. Pay close attention to your distance, altitude, and return to home settings. Always set these before take off. You don't want to have an emergency and run into a tree because the altitude is set to low.
4/ Pay close attention to your low and critical battery settings. Make sure you have these set to a comfortable level. I believe default is 25% for low and 15% for critical........ (someone correct me if I'm wrong)
5. Know what happens when you hit critical battery (your drone comes back home but you can still steer it. You can't adjust altitude)
6. Pay close attention to the flight time and the status bar. It will help you actively watch your battery level and flight time. Know what the "H" is. (H being point of safe return to home point).
7. Know how to read your IMU and compass settings and how to calibrate. (I believe they're usually between 1.00 and -100 on MOD and 1500ish on compass)(There's no such thing as over calibration. Calibrate wherever you are flying)
8. Always read the status bar at the top of the go app. Don't fly when it's not ready and don't fly when you have a critical update.
9. Always, and I mean always set your home point. The drone does this by default from where you take off, but sometimes your take off spot isn't the best for an emergency landing.
10. Know what mode your in. There's P, A, and F. P mode is where you want to be for GPS and stable flight. A is where you want to be if your experienced and don't need GPS. F is where you want to be if you want to access flight modes (Stick with P for now).
11. Know what the camera, record, gimbal wheel, playback wheel, etc do.
12. Know how to update your firmware. Never update the firmware on the transmitter first. Always start with the drone. (Do not turn on transmitter when drone is updating)(know how to read the log and look for success, failed, abort).
My own personal tip and a pro tip:
Drone on first / drone off last. Never in any other order. You want to be able to control it if something happens.
Propellers on last / propellers off first. Never in any other order. You don't want your hands near the propellers should these motors spin up accidently.
Get a small table or a landing pad. It wont go into travel mode on a non flat/semi gloss surface. You don't want to get stuck in a situation where your drone won't go back into it's case.

Come up with a pre-flight checklist so you don't forget any critical steps in setup.
Try an app like UAV Forecast to help you decide when, where, and what time it's good to fly.

All in all, there's a lot of good advice on these forums. Be safe, fly safe, and don't do anything courageous as you learn. This drone is snappy and it will get away from you. Less is more.
