I read a very nice article which summarized some relevant concerns of our advancing technology. It dovetails with the idea that there are certain warning words I've discovered in myself when I'm about to procrastinate.

They both deny some aspects of reality.
"Just" suggests that whatever it is I'm doing will not be impacted by a moment's diversion. However, it is the diversion at all that disrupts the task, not just the time taken.
The latter "should" is trickier. It implies circumstances which do not exist. While perhaps "I should be reading x, y or z" - the reality is that I am not. "Should" then does several things:
Without that information, "should" becomes both:
Certainly other warning terms exist, both subtle and those less so, and I'm not about to write a letter asking these words be removed from our vocabulary. But when attention has a tendency to waver, it is good to consider that there may be warning signs.
