Personal Productivity and Creativity

Advice about getting productive makes up the core of Lifehack’s content, so naturally our most popular and most talked about posts this year were just that. From developing the right mindset to promoting creativity to finding inspiration and motivation, we offered tons of advice on getting things done.

My incomplete series on getting back on track with a productivity system, “GTD Refresh”, was quite popular but was never completed. The next step for me was supposed to be eliminating my email backlog and adopting an “Inbox Zero” approach, but frankly, email won. This year – I’m going to try again in 2010 and so you may well see more “GTD Refresh posts in the not-too-distant future.

• GTD Refresh, Part 1: Getting My Head Together
• GTD Refresh, Part 2: Contexts and Calendar
• GTD Refresh, Part 3: Projects
• GTD Refresh, Part 4: Getting Sorted
• GTD Refresh, Part 5: Building the Weekly Review Habit
• GTD Refresh, Part 6: Decisiveness

2009 was bookended by two publications with something to offer the would-be personal productivity expert. David Allen’s Making It All Work revisited the core concepts of GTD and expanded on elements that had been weakly developed in his earlier work. You can read my lengthy review here: (Part 1) (Part 2) (Part 3)

And our most popular series, my “Back to Basics” posts from 2008, were collected, revised, and expanded (with 2 new chapters) in the release of Back to Basics Productivity which will be joined in 2010 by several more ebook releases.
