Never assume that you know it all.  Even if you did have all knowledge and
wisdom, your world is ever expanding.  Consciousness
is unlimited.  You are one cog in a
self-informing system.  As you learn, you
grow, and the growth continues eternally. 
With so many conscious beings—all individual aspects of the One Divine
Mind—learning and growing at the same time, constant change and growth is the
norm.  When you assume the position that
you know it all, you are stunting your growth and that of the whole.  Maintain a state of “beginner’s mind” with
room in your cup for more, and life remains the adventure it was meant to be.
