"The great arises out of small things that are honored and cared for. Everybody's life really consists of small things. Greatness is a mental abstraction and a favorite fantasy of the ego. The paradox is that the foundation for greatness is honoring the small things of the present moment instead of pursuing the idea of greatness. The present moment is always small in the sense that it is always simple, but concealed within it lies the greatest power."
Eckhart Tolle, A New Earth - Awakening to your life's purpose, chapter "Your inner purpose".
This reminds me of this quotation from Gandhi (in french).
