Study without desire spoils the memory, and it retains nothing that it takes in
Italian polymath of the Renaissance whose areas of interest included invention, drawing, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.
We are not rich by what we possess but by what we can do without
No one can construct for you the bridge upon which precisely you must cross the stream of life, no one but you yourself alone
The true hero is one who conquers his own anger and hatred
Ignorance, the root and stem of every evil
The future belongs to those who believe in the beauty of their dreams
Friendship improves happiness, and abates misery, by doubling our joys, and dividing our grief
