The title of this post would perhaps pull up "Thoughtcrime" and other related tropes (religious heresy among them probably, wonder how far back this particular trope goes in recorded human history).
Fortunately we have an extremely powerful fuzzy narrative pattern matcher in our heads and with a bit of effort and interpretation people would still get useful advice from the method.
1. We suck with memory. We re-write memory every time we recall.
2. We suck with delayed gratification. No other animal had to invest. We haven't evolved past that.
3. We suck with time estimates. The engineering trope of "3x the amount of time you think the project would take" illustrates this point. There is something in Pragmatic Programmer, too.
That is why we need calendars, planners, and timers. People who rely on their conception of time are ignoring the limits of their underlying OS.
Presenting mindfulness in a form that can reach the people who are not easily moved by the older forms of "evangelism" (e.g. monks living in poverty in a monastery, doing good works in their community) seems to me like a highly worthwhile pursuit.
[EDIT] ... yes, even if the concealed motive is to sell copies of yet another book about mindfulness.
