First and most important thing: Take your time.
Do not expect that you will be able to fly and control the drone under all circomstances from the beginning. Though it is not difficult to do simple actions, unecpected things will happen and challenge you. One of the sources for crashes is over-confidence (believe me, I know what I am talking about!). Start on a field, take off, and try basic moves in an altitude of maybe 30 feet (10 meters). Fly forward, then backwards, move left and right and so on.
Confusing in the beginning will be the dronereaction after you mad a 180° yaw. Left for you becomes right for the drone, forward becomes back to you etc. Then get in for higher altitudes and longer distances, make curves and so on untill you reach the distance where you can hardly see the drone.
Also try RTH, just to see what happens. Doing so and seeing the result will give you confidence. Another thing to do (not at the first flight!) is to switch of the controller and see what happens. Is a scary moment if you do so, but it also will give you confidence in what happens when you loose signal.
It all will take time, depending on the weather a few weeks, but it is worth it. Crashing a drone is never fun (if you are the pilot and owner), unless you get payed to do so.
