I love this game, even if I rarely buy a ticket. And I honestly don't know how anyone can say they don't know what they'd do with all that money. I have lots of ideas!
First things first, I would hand my notice in but work until the end of the school year as I teach exam classes and I couldn't just drop them.
This would give me time to get some financial advice and hire my personal assistant who I would task with putting my house on the market, looking for a suitable new property for me and one each for my dcs, researching worthy causes for me to support, and booking my upcoming luxury holiday(s).
During this time I would indulge in shopping trips to London and Paris, spa weekends, splash out on friends and family, hire a personal trainer, nutrionist/chef, cleaner, gardener etc. I may even sub-contract some of my marking 😁.
I would also be visiting the properties selected by my PA, who would take care of the move from A to Z when the time came. I would like a five bed character property with a well-established garden in the New Forest, within walking distance of at least one good pub.
Then, come July, I would be off on the first of many holidays on my list before coming back to settle into my new house (which my PA would also have had decorated according to my instructions). And I would finally get a dog or two.
I would then spend my time walking, gardening, reading, listening to music, eating out and generally enjoying a quiet country life, with regular trips to London for the theatre and museums, the odd week in Europe and then one or two longer far-flung holidays per year. My "work" would be keeping up with how my worthy causes are doing, and seeing how I could further help.
I would of course make sure my elderly relatives were getting the best care available, set up trust funds for my dc with the condition that they have to gainfully employed or involved in charity work to benefit from it, and help out dear friends to make life easier.
So, I think I would very much like the full 68 million!
