Think of the absolute best, most fantastic feeling of pure bliss you have ever felt in your life. Remember the way it made you feel both mentally and physically. Remember the way the muscles in your body felt. Just the pure happiness, dwell on that for a minute. Really feel it.
Now . . .
Think of the deepest, darkest, smallest, coldest and wettest hole in the ground. And that ground is in the deepest, darkest, back corner of a cave beneath an iceberg, in the middle of the cold season.
Can you imagine sitting in that hole, alone with not even a flicker of hope that you could one day get out and all you have is that memory of your happiest moment?
How do you get out of that hole? Now remember you are physically alone because nobody else even knows that hole exists.
