Lol - well I think doing something new every weekend before you die could clock up a fortune, but anyway, after thinking seriously - and then not so seriously ......
1) Fall madly in love
2) Everyone should have at LEAST one job change during their lives!
3) Make a parachute jump for charity.
4) Go to that gig you'd always wanted to see - and dress up like a teenager again.
5) Beg, borrow - or just ride pillion on the biggest, fastest motorbike you can find!
6) If you haven't already done it dozens of times - go skinny dipping
7) Learn something new - take an OU course or take up weight training or some other hobby.
8) Write a book
9) Hitch round the country
10) Spray your car in bright colours and "announce" yourself!
