Thinking Out of the Box

Thinking out of the Box has been a trendy saying for some time.  Yet, are we practicing it?  Or, do we know how to do it?  Or, are there any barriers holding us to do so and etc.  Finally,  Thinking out of the Box remains a trendy term than a successful behavior change.

I like to relate Thinking out of the Box to Think Big.  When I am thinking Big,  is it big enough to be out of the Box?  Or, what I was doing is only thinking bigger within the box. 

I dont agree.  I dont agreed thinking is an act within a box.  If yes, the box is the limiting belief given to me by myself.  More important is that do I aware I am giving a limitation to myself when I am thinking.  I may assume thinking big will only happen if I let go all the limitations.  Again, do I aware what and when the limiting belief dominating my thoughts.  Over here, my body may be a good indicator.  When I feel relax, I did let go.
