I don't know for sure that it is true. I do know that it is a common problem in the states, but that doesn't mean there isn't anyone (or even entire cultures) that manage to stay focused all day. Or at least focused to the point where improving focus gives minimal returns.

In either case, whether others struggle with my problems is only relevant insofar as I can find and learn from people who have found ways to overcome those problems.

I was trying to state that how well one can stay focused is something everyone works on their entire life / struggles with in varying degrees

How do you know that is even true? And even if it were, how and why is it relevant?

That "everyone" is on par with the generic "we" and idiocy of prime order.

But after joining the crowd in the bullring and reading the above, it doesn't look like I've internalized this idea at all.

Reading it back as it's written, it appears I'm projecting my personal problems onto others. The process is similar to using feelings to determine the state of the outside world. I also likely wrote it to justify the behavior I go on to describe in the article.

As I'm sure it is in the lives of most.

What exactly is your point with this footnote? Do tell me now and try to come up with something at least a bit close to the root of it so as you shed perhaps the tiniest bit of idiocy rather than further add to the mountain on display.
