"I'm all in."
"All in", at least in Phil's world, comes from the game of No Limit Texas Hold em. In the game it means "I am betting every chip I have on this hand. I am putting all my resources behind it."
It's both a scary and powerful thought. If I'm right - I could double my money. If I'm wrong, my game is over. I am possibly saying no to all future hands to focus all of my energy on this one.
Going all in is exciting. It's fun.
In real life - if you want real success - it's also mandatory. When you have an idea that's good - you put all of your energy behind it. (You may or may not have to put all your money behind it... the analogy isn't 100%. Or maybe it is - if I have the biggest stack of chips at the table, I never have to put 100% in to go "All In" - my opponent does though.).
Steve Jobs was all in on the iPod. Then the iPhone. And the iPad.
