What would you do if your teacher told you to stop using the word "happy" so much? If you had the Big Picture Thesaurus, you might thumb through it until you found "happy" under the subject of "feelings". Then you'd find your options: "glad,""joyful,""cheerful,""delightful," and "upbeat". At this point, you might be scratching your head deciding which word to use, but once you find it you'll feel glad, joyful, cheerful and delighted for your efforts.
