While I agree that it’s quite common these days for people to use ADHD as an excuse for why they can’t do X, in this case I don’t think your dismissal of others’ symptoms is fair. It’s generally true that people with ADHD are unable to form and maintain routines without significant external incentives and that maintaining those incentives is a precarious and exhausting endeavour. As many others in this thread have noted, they lack habit forming momentum and end up quickly depleting their “willpower” since it’s constantly necessary for even the smallest of everyday tasks. Their routines are also easily disrupted by a change in external input and it can be quite hard to recover. That said, different people experience more or less severe symptoms and if you are able to tolerate ADHD medication it can significantly reduce the effort required.
