Personally, one of my go-to content sources is TED talks.  In particular, I have enjoyed Simon Sinek.  He’s an author best known for popularizing the concept of "the golden circle" and to "Start with Why.”  In one of his talks, Sinek encourages us to understand “why” we pursue an idea, and then dig into the “how” and “what” later.  By doing so, the result is a vision and energy that transcends the morass of tactical details.  A prime example … Steve Jobs is the iconic “why guy.”
