It's easier to act your way to a change than to think your way to a change.
Well, maybe not 'easier' - just more successful.
Take push-ups... or struggling with writer's block... or sluggish sales....
Doing push-ups will accomplish the benefit of push-ups better than reading The Encyclopedia of Push-Ups, 16th edition (I kinda wish this was really a book).
(This means acting - as in, doing... not pretending - the fake-it-til-you-make-it pretenders alternative.)
Whether this means ignoring our likes and tastes and embracing our audiences' likes and tastes, or trying and testing instead of creating perfection, marketing that works is marketing that works.
It also applies to transforming culture, teams, people (even writers - the most notoriously difficult people to embrace change over preference) - acting your way to change is a more reliable guide to transforming how we experience change than writing a memo, hosting a retreat, or indoctrination through retraining.
It may not be easier, but acting our way to change will lead to change.
