Fun is the enjoyment of finding pleasure in an activity. Fun is very personal and to some extent unpredictable.
Whether you're playing or pursuing an occupation, it is important that you must have fun, at least hourly, if not with every minute. Even if you engage in a somber occupation associated with sadness, you can internally 'have fun with it', without offending anyone.
You will awaken faster and create more efficiently if you adhere to the Five Tasks of Life. One of the Five Tasks is pursuing your Duty. What does this mean?
Live your own biological life. You have no idea how long you'll be on your planet as a human lifeform. Barring any interruptions (an accident or terminal disease), you'll probably die in your seventies or eighties. So what are you gonna do until that [fateful] day? What will make your life full and complete? What will be the opposite of a wasted life? Find your duty and do it with passion.
