It is essential that we all maintain happiness on the inside... and if anything makes you happy then keep doing it, just make sure it's civil! ;)
But besides doing what you love and enjoying lifestyle, it is also important maintain an organized and lively lifestyle, not a lethargic and glutton of a lifestyle. If you want the most out of life, you're going to need to push yourself to higher limits! Bruce Lee once said:
"If you love life, don't waste time, for time is what life is made of."
If you waste time you're wasting your life! But also, remember what John Lennon once said:
"Time you enjoy wasting, was not wasted."
Try to keep a bridge between your time to stay efficient and your time to enjoy, if you can have it both ways! You can separate it into 3 things... fitness, study and leisure. Make sure you're body is at it's optimum level: you won't feel lazy to do anything anymore. Study: continually make sure you're on top of you're school work, or if you're done with school try to keep your mind active, remember anything that's not used over a long period of time rusts, whether it be iron, food or your own mind. Learn a new language, memorization techniques, learn to write with your other hand, take another college coarse!! And finally... leisure. This is when you can enjoy yourself and stay happy. If you want to get started organizing, try to keep a small book around you and write down everything you want to do during the day. Check it daily and cross what you've done out, your mind will listen to what's written on paper more than what it tells itself!
That is all for now, stay happy and organized and live your life mates!
