It’s not what you look at that matters, it’s what you see.
Henry David Thoreau
Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.
You will never do anything in this world without courage. It is the greatest quality of the mind next to honor.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
Ralph Waldo Emerson
