I think the closest thing I have to a 5 year plan is a list of goals I'd like to achieve before turning 30, both small and large. I do also have a list of plans but it's very short term (1-6 months only) and is more practical, everyday stuff than large things I want to accomplish, if that makes sense?
I think the most useful part of it is not completing the goals themselves, but taking the time to sit down and reflect on what I actually want. I'm not going to cry on my 30th birthday because I didn't tick off some goals but I do feel that now I have a sense of clarity over what's important to me.
I try to keep it flexible as well. I used to be borderline obsessive with life plans and if that's taught me anything, it's that life has this annoying habit of getting in the way of those plans
but at the same time, events that I thought were ruining my life ended up with incredible, and unexpected, outcomes. A while ago, my 5 year plan would have been along the lines of "move to Milan - work and live there for 2.5 years exactly. Use free time to learn how to make the perfect lasagne, speak Italian fluently, visit Florence after exactly 64 days of living in Italy", that kind of level. While I'd still like to live abroad, now I haven't bothered to specify whether that's Bali or Canada, five years or two months. It's still a goal, but it's more adapted to life
