Find comfort in the knowledge there are mountain peaks you will never climb, sunsets you will never see, flowers you will never smell.  The world is larger than you and me.  What a nice thought. 

Also find comfort in the experience of climbing higher than expected, seeing further than your imagination, knowing more than you can touch and smell.  Again the world is larger than we might guess.  "For now we see in a mirror dimly, but then we will see fully, even as we have been fully known." I Corin 13.
