I remember hearing on some TV show, the mum said "boys can only see 20 mins into the future" and it's something I quote to my husband all the time.
Some boys are like that, but so are some girls, so not really true.
My DH is a planner in the extreme and he gets stressed/anxious about even small and irrelevant things. Planning something like a holiday or a day out is a nightmare because he plans for every eventuality. We always, literally always, arrive early because he's planned for all kinds of unlikely disasters! We have a sat nav in the car, but he also has printouts from google maps "just in case", and he also plots alternative routes through one of those large car road maps! Same with trains or buses, we never get the one that gets us there in time, we get the one before that (just in case the later one is cancelled or running late). We've got a mini survival kit in the car, drinks, snacks, blankets, torches, spare clothes, tool box, etc. For Christmas or birthdays, he's always bought his presents, literally, months ahead, so there's no opportunity for anyone to make a suggestion closer to the occasion as they're all bought and wrapped! He spends hours on google before we go anywhere to look at, say, a plan of an attraction like a zoo, looking at pictures/videos of it, so that he can "route march" us round it in an efficient manner, planning the optimum route so that we arrive at the food court/cafe around the "right" time for lunch, etc. There's no scope at all for any spontaneity. If he's going to do some DIY, he buys every conceivable tool and material he may need and then takes/sends most of it back unused (of course he checks the returns policy before he orders anything online to make sure he can return it freepost! - he'd never get caught out buying something that he couldn't return or would cost him postage!).
DS is the same. He did his homework on the day it was set, not the night before it was due so was never late with handing anything in, never got a bad score in a test because he'd forgotten to revise, etc. He's always on apps "planning" journeys, planning his day trips to away football matches, etc. - if the journey looks difficult or connections etc are tight, he'll decide not to bother going. He must have picked it up from DH.
'm pretty well organised, but DH and DS are on a different scale of pre-planning, worst case scenario planning, etc. Of course, it means things aren't forgotten, mistakes aren't made, etc., but, by God, it's exhausting living with them, and their constant "withdrawing into their shells" as they concentrate on the minute detail of whatever future event they're obsessing about!
