Mike Vardy coined the term Productivityist.
and I think I am one. According to Mikes definition:
A productivityist is not a productivity expert. A productivityist is not a guru. A productivityist is a productivity enthusiast.
I like to study different productivity systems and try to incorporate them into my everyday life. Mike has some great resources on his site, a free productivityist manifesto.
I also bought his book The Front Nine: How to Start the Year You Want Anytime You Want. I’m half way through it and it’s got some really good information. If your interested in productivity I recommend taking a look at it.
