“ Intellectual growth should commence at birth and cease only at death. ”
Live as if you were to die tomorrow. Learn as if you were to live forever.
A man with outward courage dares to die; a man with inner courage dares to live.
Study without desire spoils the memory, and it retains nothing that it takes in.
If you can't explain it simply, you don't understand it well enough.
Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light.
