Whether you recognize it or not, when you walk into a traditional classroom environment you are mentally, physically, and emotionally preparing yourself to learn. When you walk down the hall and through the doorway into a classroom you are entering a learning environment. When you do that, you consciously and unconsciously allow yourself to engage in the learning material during class. Your goal for creating a "classroom at home" is to give yourself that same opportunity to succeed.
The challenge is your home environment might be your kitchen table, your living room couch, a spot in your bedroom, or anywhere that you can stop and think in that particular moment.
