I began to use Omni Focus after already spending years with GTD. The software takes some getting used to. Nothing wrong with Omni Focus at all but just beware of trying to learn two things like that at once!

I’d suggest starting GTD with paper (my own suggestion) to get comfortable with the methodology.

You can easily migrate to any tool later (and I’m too much of an expert at migrating between systems).

I have blogged about 5 Steps to Begin Learning GTD over here, which has links to lots of online material. Hope it helps.

Start thinking about how you want to implement the different pieces of GTD. Then READ THE BOOK AGAIN! If you don’t want to read it again, read our GTD Primer. I wrote most of it, and it was the first attempt at blogging over 3 years ago, but there has been a lot of good feedback from it. One of my upcoming projects will be a rewrite of it.

You don’t need GTD Connect, a seminar or coaching [although it would be cool]. EVERYTHING you need is in the 267 pages that make up Getting Things Done.

I have just started Making It All Work tonight and I am very excited to see what lies within.

But read it cover to cover first – don’t implement without getting an overal picture first.

I blogged recently about this and I encourage people very much >> Book >> Book >> Book

Once you’ve read it right through, second time as you implement, things you didn’t understand first time fall into place.

But there’s extra steps involved. At some stage you’ve actually got to put time aside to actually start the thing!

But before I spent any money, I found it helpful to read some of the many “getting started” articles and overviews available for free on the net. For example, if you use the iPhone, Google “GTD iPhone” and read how others are setting up their systems. This was tremendously helpful in my case.

Kelly Forrester’s “best practices” series is a great, concise resource. Download and internalize the two Mastering Workflow diagrams from davidco.com.

Once I got going in GTD, I listened to DA’s second book, “Ready for Anything” over and over. It offers loads of great higher level GTD thinking. Same goes for his current release, “Making it all Work”. It could even be read first, but there’s a good deal of mechanics that you’d better get from the first book to really get your system up and running.

One last but key “getting started” maxim: You derive benefit immediately, but it took me 2 years to really get my system optimized, and I am still making tweaks now and then.

Kudos for making this list, but come on people just get with it. Start reading!
