I only had one major plan from the age of seven: become a vet!
I'm one year away from attaining that goal, and hopefully, I won't suck at it (that's my next major goal: don't suck at being a vet).
I never thought I'd be married at 21 - to a Brit! But I always have loved the UK and have harbored a desire to live there from the age of I dunno 14 or 15. My parents sort of ruefully look back on their idea to send me to Spain for three months to live with relatives (at 15), they say "If only we hadn't given her the taste of Europe, she'd never be leaving us" ;-). They're so wrong! I studied abroad in undergrad, and while I was falling in love with my DH the idea of living in England just totally cemented itself. A few months spent visiting his Aunty and Uncle in Yorkshire (spread over a couple of years) and my absolute undying love for Yorkshire was born. :-)
So long term plan = graduate vet school, FIND A JOB! (hopefully in Yorkshire/somewhere close enough to Yorkshire that I can visit often), be GREAT at said hypothetical job, travel, more cats, babies?!, train a dog to run agility courses, get rich (haha), farm?! (with goats - make goat cheese and goat cheese products -, geese, ducks, cows...maybe a horse...they're too much trouble really), start a cat sanctuary or contribute something meaningful to the welfare of animals, play with grandchildren, die (preferably at v.old age!)?
thats the "grand plan" who knows what will happen!!! (except for the last bit, as someone else pointed out ;-))
