40 things to do before I'm 40

The other week I saw an article in the Sunday Times about '40'.  I turn 40 in September so this definitely interested me.  

With the big 4 Oh looming on the horizon (a mere 6 months away) I thought I should set myself some goals.  40 is kind of grown up so what grown up things should I be attempting in the next few months. 

1. Go & see This is 40 (OK start with an easy one & seems an obvious choice)
2. Visit Stockholm.  I have been promising myself this for the past 2 years so better get organised.
3. Lose weight.  I want to be wearing significantly smaller knickers for my birthday party
4. Arrange a kick ass party
5. Write a letter to myself
6. Spend a night in a hotel by myself
7. Drive on the motorway without fearing I'm going to die
8. Climb a mountain
9. Get something published
10. Do a yoga class
11. Learn to make profiteroles (choux pastry scares me)
12. Stop caring what other people think of me
13. Learn to walk in heels
14. Find a 100 movies to watch before you die list & make sure I've watched at least half of them (well I'm middle aged, I have another 40 years to see the rest)
15. Read the all books on my bookshelf
16. To learn to make caramel shortbread
17. To start writing letters again.
18. To start doing sit ups every day. (see no 3)
19. To start reviewing my photos, printing them off & organising them in photo albums (& make an album of my youngest daughter's 1st year as I did for my eldest)
20. To write something every day. (see no 9)
21. Learn to meditate
22. Accept a compliment
23. Sleep under the stars
24. Do an evening class
25. Employ a cleaner
26. Go to the theatre more
27. Buy a piece of art that I love
28. Get a decent pair of jeans that make my bum look great
29. Visit tourist attractions in London that I have never been to
30. Go dancing/ Pull an all-nighter (it's been a few years since I've done that)
31. Go & visit a psychic (they'll be expecting)
32. Cull my facebook friends list & have no guilt in doing so
33. Blog more regularly (see no 20, well maybe not every day)
34. Learn to like myself
35. To be able to fit back into the pelmet skirt I wore when I was 18 (see no 3) & then throw it away as I am too old to wear it!
36. I will buy a full length mirror for my house
37. Go ice skating & not cling on to the side
38. Try something new every week (food/ activity/outlook)
39. Swim in the sea.
40. ???

I am now truly stuck.  Help please, I need suggestions, what do I NEED to do before September?
