When animals meet with pain or obstacle, they back out or find alternate route.
Humans are endowed with other options which are that:
First of all, you can break through the obstacle such as making road through the mountain.
Again, you can transcend it such as flying over it.
You can transform it such as making bridge over two mountains or over water; or such as building a spectacle mansion on the obstacle mountain.
Always remember that in life, you will always have to deal with the two forces of pain and pleasure; and that is what the Earth game is about.
Be strong oh child of God!
