Just saw about ADHD, OP.
I'd say that explains your decision making process fully.
I'm also diagnosed, also get "itchy feet" and I only move on a stab-of-the-map impulse. In fact, always moving (including between countries) in search of something... A change... An adventure... Is one of the defining symptoms for me.
Personally, I've learnt that I can't necessarily trust my brain when it comes to large decision making (particularly relating to moves/property) and for a particular reason - no matter what logical reasoning I come up with to "sell" the move, it's actually just a compulsive part of my behaviour. It's ADHD.
I expect your rural project (as that's essentially what it is) will only be "shiny" whilst new... And then that stifling feeling again, the next dream, the next project, the next move.
I've realised that what's exciting for me, can be quite upsetting for others. So I'm not going to move to Peru to farm avocados. Not yet 😜
I'm trying to live BIG where I'm at in this moment. Straight out of lockdown blues I bought a run-down charming wreck of a Victorian property in the middle of inner-city HMO land. It's a complete "zoo" around here and the house will be rebuilt and restored by my own hands. Yeah, it keeps me awake at night but also gives me purpose & keeps that dreaded boredom threshold at bay.
I've made a decision to love it here. To grow old and eccentric in my charming house. And if I need a Project in future then I'll figure out how to earn a Blue Plaque rather than move 😁
