I know exactly what you mean Jess - I currently have 2 parallel lives; one without winning the lottery, one if I do. I suspect we are often 'on the same page', and probably the same websites lol.
I think here in Oceania our chances are roughly 5% (if I remember correctly there were approx 15K applications last year and 900 selected). Some days, I don't think about the lottery too much - regular life keeps my feet well and truly in the 'here and right now!", but other days I think very heavily of the choices I will have to make should we get selected.
Will I be disappointed with a no in 2 weeks? Yep, I will. But I will very quickly shrug it off and keep doing what I need to do here.
And then start all over again come October lol
Whilst it is important to live your life as you have it right now, there is nothing wrong with saying "yes, I like my life, but I think I would like another one now please
"
