He intended to buy a much-needed reliable car with the money. However, he recently saw a documentary on beekeeping and honey making and decided to invest all of his tax refund and much of his savings on equipment to start a new beekeeping business. He is so sure that he will be successful in this pursuit that he quit his job. Although he has been staying up late making plans for his business and has only gotten a couple of hours of sleep a night for the past week, he is full of energy. This is the happiest and most confident that he has ever felt. His nonstop talking and boundless energy are exhausting his friends.
