False dichotomy. You can both take measures to address an issue you have, and still know that won't always solve the problem. Being really early sometimes is the only option, but if you're always doing it, regardless of how critical it is, you're wasting a huge amount of waking life.
Everyone wastes a huge amount of waking life on something, whether it's sitting around waiting for an event to start or watching TV or scrolling social media. So what.
So, knowing how much time and effort is required to maintain such responsibilities, you think someone with a similar situation, but who also has trouble being organised in general, has extra time to twiddle their thumbs for half an hour or something, before every single obligation with a time attached, just to be sure they don't get distracted? Do you have any comprehension of how ridiculous that sounds? If you're less capable of completing tasks you need more time than a typical person to do so, not less. They don't give students with ADHD less time in exams to ensure they can break task and put their pens down on time.
Still pushing those preconceptions, eh? Is this how you approach everything you could learn from? Assume you know all the answers before actually studying? Your teacup is full.
