No need to be scared, a lot of people post unhappy experiences on here and it overshadows the good times. We learn by doing, take it nice and slow...after reading the instructions and having a play with dji go simulation mode.
Pick a nice quiet spot on a still day, with no over hanging trees.
Turn on your remote, drone, then phone, make sure the silver switch on the top right of the remote is in the top position (it had 3 positions), left switch does not matter yet. It will take a few minutes to warm up, so be patient. The dji go app will tell you when its ready to fly, use the auto take off function...touch the button, then the slider that appears. Then do nothing, she will take off and hover giving you time to stand open mouthed at how cool it looks. Then just try out the sticks, gently, one at a time and see how it reacts. Go up, go down, back and forward a bit, it will fly faster than you think. Bring it down gently with the left stick and when settled on the ground it shuts its rotors off.
You don't have to fly a long way to have fun with it, just take it at your own pace and have fun. You will make mistakes, we all do. If in any panic just let go of the sticks and she will stop and hover, giving you time to think.
Just dont try flying indoors.
