Inertia

The only thing impossible is this world is not learning something incredible when you walk to the edge, push a bit harder, go beyond your comfort zone. The mind is elastic, the heart in motion, neither intended to sit idle, hardened by habit or molded by monotony, but rather to continually evolve and expand by exposure to new experiences and the vast wonder of this playground we call "earth."

Life is either a daring adventure or nothing. Security does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than exposure.

Helen Keller
