15．
Are you bored with your daily routine？Here are some things you should try before you are 18，because after that it's too late!
Camp out in the garden
If you don't have your own garden，find a friend who has one!You will need：two or three friends，a small tent，sleeping bags and warm blankets．Take a lot of food and drink with you into the tent andplay games until it gets dark．When it gets dark，tell ghost stories，and at midnight，eat all your sweets．
You will need a torch or you won't be able to see all your sweets，and it might get a bit too frightening．
Learn to swim
Seriously，this is so important it could 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．
Collect something
One of the best hobbies for under-18s is collecting things．You could collect rare Chinese stamps，or you could collect things that make you remember what you've done，like cinema tickets for films you've
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．
Try at least one kind of team sport
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．Besides，team sports like basketball，football and baseball can keep you fit，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．
Write your family tree
When you are young，get to know all the older people in your family and find out as much as you can about when they were young．Draw a family tree and make notes about each person so that you won't forget．
