To move towards being more single-tasking, consolidationary, and focused (and thus slightly away from multi-tasking, expansionary, diffused) -- I started a training regimen and a new way of thinking.
I announced it in this video a couple days ago.

Of course, lots of techniques work when you first try them out. Hawthorne effect, etc. Is the technique fragile, robust, antifragile? Is it worth using repeatedly? Is it easy to reboot if things go wrong? Is it trite? How difficult is it to start doing if you've been off of it?
These questions aren't answered yet.
