observations on 50.000 ft
GTD is imo the perfect methodology for things to be done (as simple as possible, as complex as needed), on the "horizontal axis".
It is furthermore of maximal interest to me for incorporating the higher levels of prospective (vertical axis).
Anyhow, recently I found that the hint to review the level of 50.000 ft only once a year is misleading, at least for a lot of people.
Religious people, who are bound to Christianity, Jewish faith or Islam, attend a religious service once a week. This is, in GTD terms, the level of "why I am on this planet", i.e. the 50.000 ft level.
When a religious person is praying more often, let's say on a daily base, there is a connection with the 50.000 ft level even on every day.
This aspect seems a bit neglected and therefor obscured by the advice of touching the highest level only once a year.
What do you think?
