>I think you missed the word “before” in their comment.
Nope. Didn't miss that at all. What is it that the kids call it these days? "Adulting?" It really ain't that hard.
Then again, perhaps I'm some sort of superman, or maybe paying my bills on time is my super power.
Somehow I've managed to pay all my bills, keep up my house and renew multiple domains for decades. And it wasn't even hard to do. I have a whole bunch of payments I need to make that aren't simply monthly payments of equal size -- and yet I manage to do so without issue.
Do you think that's unusual or uncanny and folks shouldn't be expected to manage their financial affairs competently? Is that your point?
Then again, millions of others seem to do that just fine too. As I said previously: If it's important to you, you tend to make sure it gets done.
If you (or anyone else) is unwilling or unable to do so, then you should hire an accountant to take care of it for you. Or not.
Regardless, I take care of myself without issue. If you and/or others cannot or will not, that's a you problem.
