Three Things to Do Before You Are 18
Are you bored with your daily life? Here are some things you should try before you are 18, because
after that it's too late.
Learn to swim
Seriously, this is so important that it can save your life. If you can't swim well, you won't be able to do
water sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make
sure you do it.
Try at least one kind of team sports
Being a good team player is an important skill in life. You can't just think of yourself, but have to work
well with other people. Other advantages of team sports like basketball, football and baseball are that
they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too -
you'll go to lots of parties and make many friends.
Collect something
One of the best hobbies for under - 18s is collecting things. You could collect kinds of stamps, or you
could collect things that make you remember what you have done, like cinema tickets for films you have
seen or emails from friends. The best way to collect is to have a special album to put your collection in
and to write what each thing means to you. That way you won't forget.
