“Who am I?  I
don’t matter at all.”  And with that
thought you do a disservice to divinity. 
Even the smallest creature has the same value as any other, for all
is a manifestation of Divinity, of Source. 
All is Spirit experiencing existence. 
May we use the wave in the ocean analogy?  You may express yourself loudly and boldly as
a benevolent tidal wave, or as the smallest ripple.  But that ripple, it is so small that it seems
to blend in completely with the ocean so that it is indistinguishable from the
Source.  And so it is.  By not expressing itself as a giant wave,
reaching out and crashing boldly against the shore, it may not have as much of
an effect and others may not take notice, but does it have any less of the
original Source power?  Not at all.  The same potential, the same Power, the same
essence exists in the entire sea, and you are a wave of That, no matter how big
or small.  Value that.
