Think Big
 John Maxwell wrote in his blog, Think like a Leader , "Nothing hurts a leader like small thinking.  When you're at the top of the decision ladder, you need to bring your A-game to every situation. Pushing the envelope with creativity and vision is essential for a leader.  Successful leaders understand that if you think small, you stay small.  Do not let the fear of success or failure dissuade you as a leader from thinking big."
If the Wright brothers hadn't thought big and set big goals, humans wouldn't have been flying today in airplanes. Before you can achieve big things, you need to think big things.  Some people say that thinking big is the key to accomplishing your biggest or most complicated goals, but it's hard to know where to start. Giving yourself some time to sit down and really think about what you want to accomplish is just the first part of thinking  big.  See below from   wikiHow website  article, How to Think Big co-authored by Paul Chernyak.
1. Schedule thinking time.  Set aside 90 minutes to think about new projects or goals.
2. Entertain the impossible.  Thinking big requires you to move beyond thinking realistically and toward what might seem improbable or even impossible.
3. Step outside your comfort zone . Let yourself feel a little uncomfortable when thinking about new projects or goals. If you're not a little scared of what your're coming up with ,  you're not thinking big enough .
