My good friend William Jonathan asked me the other day what I was reading that helps me develop in life and leadership. Here is a variety of things that I like to read consistently to keep me sharp:

THE BIBLE (This helps the most. I use the New Living Translation.)

Fast Company (business magazine on new trends in business/new ideas/business leaders)
Relevant Magazine (God. Life. Progressive Culture.)
Inc. (Entrepreneur magazine)

BLOGS (I subscribe to these blogs and get them via email)
Guy Kawasaki (marketing guru)
Seth Godin (marketing guru)
Brad Lomenick (top dog at Catalyst)
Mark Batterson (life and leadership)

I like to read a lot of material from the business/marketing/entrepreneurial world. I believe that many business principles and the stories of leaders in these areas can translate into life and ministry seamlessly. Hope it helps!
