“It takes me 15 minutes to get to my destination. I should leave 5 minutes earlier than I need to in case there’s traffic or whatever.”
Set an alarm for 20 minutes before you need to get there, and leave when it goes off. Done.
I will absolutely trivialize it because everyone I’ve ever known that’s like that simply leaves at the time they’re supposed to already be somewhere. Or yes, they get distracted and start working on stuff that they know will take 30 minutes when they need to leave in 10. Thankfully we all have mini computers in our pockets that tell us exactly how long it takes to get somewhere that can also easily set alarms.
You clearly don't have these issues, and I doubt you care about anyone who does, because your "Oh, come on." response positively reeks of 'that's not my experience, so other people's can't be that different.'
It's never just one thing like travel time, it's scores of steps in a routine, which aren't always the same, and can easily be derailed by anything unexpected. You can estimate how long something you do frequently will take, based on how much time it took previously, and still get an inapplicable answer because distraction is a constant problem, and the executive function deficit means you literally do not think 'don't do that, get back on task' in the moment. You know how long everything should take, and still struggle to apply that when you're doing the routine.
Everyone has issues. For instance, I have idiopathic hypersomnia - I'm tired literally all the time. I don't get to say "Sorry wife, I'm just not going to be able to work."
There are things we're good at and things we need strategies to mitigate. I may not have ADHD but I have friends and family that do, so I'm familiar enough with it. What steps in a routine are needed to leave the house? Find your keys and wallet? Always put them in the same place. Go to the bathroom and maybe check how you look? Set that timer I talked about 3 minutes earlier. Other people with your condition can handle it; so can you.
Why is it that you think you're offering life-changing advice? What makes you think I don't use repetition? What makes you think I've never tried timers? What makes you think I'm the exact same as person as your friends and family? What makes you think I don't also 'just get on with it'? Do you even think about what you're writing?
Everyone else manages to do it, you're not special. Be on time, or be a NEET I guess. You've decided you'll never be able to function properly so yeah you probably won't.
What a fuckwit. No, not everyone else manages it. I decided no such thing, you're just fabricating bullshit to feel better about being an arsehole to people who weren't born neurotypical. I have a career with pretty good pay and benefits, and you obviously didn't read anything else I wrote about managing my issues. I'd rather be late than a sociopath.
