Acquiring knowledge is the most fruitful effort.

Don't be afraid to study hard: knowledge never exhausts the mind.

If you want to be strong, exercise; if you want to be wise, study; if you want to be happy, smile; and if you want to be invincible, love.

Teach the ignorant. Study the wise. Avoid the foolish. Embrace the enlightened.

Rigorously comb through the pages of your life until you can even speak its broken dialects fluently.

One who thinks for himself is a threat to his enemies, a refuge to his acquaintances, a prize to his friends, and a gift to the world.

Think twice as much as others.Study twice as much as others.Work twice as much as others.Give twice as much as others.
