Do not be afraid to fly your drone, take it out, some place where you will not bump into buildings, fences, trees, walls, etc…
I've attached a link to a video that shows basic flight maneuvers every beginner should know. Practice these maneuvers, just do not go out and see how far or how high you can fly your drone.
Learn to fly it by sight, not by looking through the video. Learn to fly it when it is flying away from you and learn to fly it when it is flying towards you (it's backwards then…) and if I did not say Practice enough, I'll say it again, Practice, it is the only way to develop "Muscle Memory" where you stick inputs will become second nature and you will be less likely to accidently fly into an object verses flying away from an object.
Now Go have Fun!
