The kind of motivation anyone needs is to see what you are doing wrong so you can improve. You can't fix something in your life unless you know what you are doing that is either hurting you or slowing you down.
So back to the subject of dreaming big. There are three books I've read lately: Procrastinating on Purpose, Take the Stairs, and The ONE Thing. Two are by Rory Vaden and the One Thing is written by Gary Keller (and Jay Papasan). These books have fundamentally changed how I look at my life. Yes, I've always been a big thinker but I never did anything about it. Had great ideas and then didn't follow through.
Well, No more! Australia here I come!
