Summarize this article:

The taming process will take time. You need to get your bearded dragon used to you and you will also need to learn its habits and preferences. Don't physically isolate the bearded dragon by sticking its cage in an unused portion of the house. While you don’t want to subject the bearded dragon to too much noise and activity, having it out where it can be a part of the household buzz will get it used to having humans around. Consider placing the cage in your living room if it is not to loud or busy. If your dining room is near the action of the house, but not constantly in chaos, then that might be a good location for your bearded dragon's cage. Set aside half an hour or more of time every day to handle your bearded dragon. This will help it get used to being handled. While you can break up training sessions into shorter 15 minute sections, make sure that you spend at minimum a half an hour a day handling your bearded dragon.
Be patient. Place the bearded dragon's cage in a central place in your home. Work on taming your bearded dragon every day.
