I just finished reading an interesting and unique novel by Mark Haddon, with a curious title "the curious incident of the dog in the night-time". It's unique because the story is told by a 14 year old gifted child who loves numbers and dreams of becoming an astronaut. It's a touching story of love and logic, of patience and patterns, of moving on and mathematics. Read this:
"And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don't even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in your life it is nice to think that they are what is called "negligible", which means that they are so small you don't have to take them into account when you are calculating something."
When you have your own difficulty and you begin to listen to the difficulties of others, it's like looking at the stars and realizing how "negligible" your difficulties are compared to those of others. It doesn't make the difficulties go away, but they become easier to face. So, always look at the stars.
