Have you had or have an ambition that on the face of it appears a bit boring, futile, sad or just daft that you wish to do? Everyone has heard of folk who want to run a marathon, climb a mountain, learn a musical instrument etc but what about the less interesting ambitions? Mine is to fly on three particular aircraft I haven't been on that are either on the way out or will be soon. So tomorrow i'm off to Madrid - hopefully on an A340. Then on Friday I'm off to Dubai on an A380. I'm staying here for a few days then flying back to Heathrow on a B747. When I think of all the time, money and effort I've put in to this trip I feel a bit of a sad weirdo but I feel sure there are worse than me out there.
