From my perspective, it depends on what one means by "review". If it means "quick glance over actions, projects, and calendar for the next day or so then making sure everything in your inbox is processed" then that shouldn't really be taking any more than 15 minutes as it is largely just getting your inbox to zero then doing a brief overview of the current commitments for the next day or so. If it means something equivalent to the weekly review then that is somewhat unrealistic for the
vast majority of people.
This is a common misconception I see regarding GTD: doing a daily review. Personally, I do not recall reading anything about doing a daily review in any of David's books or any of the official GTD materials. Perhaps it hails from the classic GTD terminology: Collect, Process, Organize, Review, and Do? People may have often misinterpreted the "Review" step and misconstrued it to be some kind of overkill "Review" session. I would imagine this kind of factor was a part of the reason for the update in 2015 to the modern GTD terminology: Capture, Clarify, Organize, Reflect, and Engage as these terms are more fitting to the fact that GTD is about the overall shift in mentality/approach and less "tactical" to a large extent.
Doing a daily review
can be helpful for some folks, however, it is not a specifically recommend best practice from GTD, as far I as understand at least, because as you are witnessing: it takes too much time, energy, and effort to review your system in its entirety that often. GTD only recommends the weekly review because it is just short enough that the vast majority of items will still be relevant and just long enough that there will be an adequate amount of change in a person's world to necessitate stepping back in order to survey the bigger picture and keep things on track.
I believe the concept of a "daily review" is so prevalent for two key reasons: people don't trust their system (yet?) and people are not using their system (as effectively?) ... which, as one might expect, leads to the former and then the later and so forth (i.e. it is a self-fulfilling process). GTD does take time and a bit of effort to ensure that the system that one sets up is not too simplistic that things still stay in one's head, yet the system is not too complex that the system becomes its own form of work.
I would take a step and ask the following questions:
What does a daily review mean to
you?
Do you
need a daily review?
Are you using your system effectively (i.e. do you resist it, dread it, find it tedious, etc.)?
Do you
really trust your system?
You will probably find that the issue is that either what you consider as a daily review is far too in-depth and likely unneeded and/or your system probably needs some tweaking to address some of the friction points.
Those are my thoughts at least. Hope it helps
