3. Enjoy the experience without spending the time
Thinking about things you enjoy can be almost as effective as actually doing the activity which makes you happy: "the part of the brain responsible for feeling pleasure, the mesolimbic dopamine system, can be activated when merely thinking about something pleasurable, such as drinking one's favorite brand of beer or driving one's favorite type of sports car. In fact, the brain sometimes enjoys anticipating a reward more than receiving the reward."
