You have heard the "a happy employee is a good employee" - refers to - ARE THE EMPLOYEES HAVING FUN. All businesses want happy employees so your ability to make most duties fun is a huge key to success. That is a gift some people are natural at where others have a hard time pulling off. Be that employee that leaves home home and work at work. Everyday find a way to make it fun and you will see what i mean. Good Luck
The job can be anything that you really feel passionate about. Rather than searching a for a job with particularly "fun" tasks, focus on how your goals and values fit into any job. Ask yourself if the job challenges you, motivates you, allows you to be creative and innovative, allows you growth, and ultimately puts you in a situation to be successful. I've found that some of the most "boring" jobs can be made fun if you are actively engaged and stimulated by the nature of the job. If you are working and it does not feel like you are working, you are in the right place.
Best of luck!
