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

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.
