I first learned about the Action Method of productivity through Behance, a company geared toward creative professionals, and a related book, Making Ideas Happen. In the book, author (and Behance founder) Scott Belsky has interviewed numerous of the creative profession's most productive people, and through that process, discovered a set of "best practices." Those "best practices" have become the core of the Action Method, a productivity system for entrepreneurs and creatives.
I've used the Action Method myself, and I love it's focus on taking action. It seems so simple, but it's so critical when we're talking about complex enterprises like running your own business.
Have you ever tried the Action Method? What did you think?
