How to Enjoy Life As a Teen

    The "best years of your life"? Maybe not, but you can learn to make the most of your high school days.

    Learn to appreciate small things. Whether it's having a computer, having friends, having a good supply of food, a bed to sleep on, family that loves you, having a decent education or simply being born in this world, value it. ____ Be happy, and life will reward you. Remember that these are the last few years you will be able to enjoy yourself without having to worry about the responsibility of an adult, but make sure you prepare yourself for when you do become one. When you actually become an adult, you'll learn to love that responsibility and you probably never want to go back.

    Choose your friends wisely. Unlike what many articles state, you don't have to be popular and have a gazillion friends to be happy. ____ Try to have friends that like you who you are, not just because you are wearing a certain brand of shoes or something like that. These are people who shop at the same store as you; not someone who will sympathize with you when your dog dies.

    Keep your grades up. ____ This also sets you up to get into a college you want to go to, which in turn prepares you for a career you will enjoy, improving your quality of life in the future. You'll get cheap car insurance as well if you have at least a B or A average.

    ____ Participating in clubs, activities, and sports increases your chances of meeting new friends. While you only need 4 or 5 close friends, that doesn't mean you shouldn't try to meet new people. Participating gives you something to do instead of sitting bored at home and wallowing in self-pity.

    Work at a job you can enjoy. Working is a great way co gain experience and to meet other people. ____ This will look great on your resume. If you can't find work, especially in this hard economic time, volunteer or make your own job.

A. Be sociable.

B. Remember the point of life is for you to enjoy it.

C. Find a hobby that is meaningful or practical.

D. In fact, many of the "friends" you have when you are popular are not true friends.

E. When you do get out of college, interviewing companies will look at your previous work experience.

F. Even though you want to enjoy your teen life as best as possible, don't idle away your time in school.

G. There is nothing more satisfying than seeing your hard work pay off in the form of A's and B's (but mainly A's).
