Big Mind and Think Big

I dont know whether I have a Big Mind or not.  However, I can decide to use my mind to Think Big or not.  I started to check whether my Think is Big or not.  This tricky thought begins to trap me in to comparison and limitation.  Rather, I try to sense the boundary of my Think.  I like to play along with the boundary and check of my response internally and externally.  May be there are still lots of room for me to expand.  I believe the most important indicator of Think Big is whether I feel the Freedom of moving around in my Thinking process.  Freedom is in fact the measure that I project for myself.  What if I believe there are unlimited space for me to search as far as I can, and even there is a wall or barrier, what I have to do is just to look in to it and remove it after understanding, there will be no limitation of my sense of freedom.  Well, I almost emerging myself in to a Big Mind.
