One of my very favorite blogs on the internet is Experiments in Lifestyle Design (The Official Blog of Tim Feriss) The blog which was launched into the Technorati top 1000 after his first book, The Four Hour Work Week,  became a New York Times #1 best seller.

Feriss coined the phrase “Lifestyle Design” which is the cultivation of “life-hacks” in order to make one’s life more efficient. Tim is also known for his application of the Pareto Principle to business and personal life. He has also taken the position that technology such as email, instant messaging and internet-enabled PDA’s complicate life rather than simplify it.

Ferris also does an interesting vlog series with Digg founder Kevin Rose called random, that you might want to check out. They’re usually pretty entertaining.

Some posts from the blog that would be relevant to F&S readers are:

• How to Lose 20 lbs. of Fat in 30 Days… Without Doing Any Exercise

• From Geek to Freak: How I Gained 34 lbs. of Muscle in 4 Weeks

• Relax Like A Pro: 5 Steps to Hacking Your Sleep

• The Not-To-Do List: 9 Habits to Stop Now

• Lucid Dreaming: A Beginner’s Guide

We very strongly recommend you check out Tim’s work, as it was a large influence in the re-design of Fit and Sexed! What are you waiting for, get hackin!

As a special bonus, here is Tim’s TED talk about productivity:
