Expectations stifle you.  They
set up a corral into which you must put your experiences.  If something that is yours for the taking
does not fit in the corral, the gates are closed, and you do not gain from that
experience.  Be careful of corralling your
experiences too tightly.  Open the gates,
then take down the fences completely. 
The world is much more broad than your thoughts, which base themselves
on past experiences.  Be open to all
possibilities.  The world, and thus the
experiences to which you can be exposed, is limitless.
