It may be an idea or a bit of information you【2】across accidentally—or a sudden【3】, fitting together pieces of information or working through a problem. Such personal【4】are the "payoff" in education. A teacher may【5】you to learning and even encourage you in it—but no teacher can make the excitement or the joy happen. That's【6】to you.

Instead, consider it a goal to【20】, a goal within reach if you use the help this book can give you.
