Spiritual knowledge is fruitful only when it is applied
Think, how hard it is to change yourself. How can it be easy to change others?
Never fear quarrels, but seek hazardous adventures.
A wise man speaks because he has something to say; a fool because he has to say something.
There are never failures -- only gained experience, wisdom, knowledge and lessons in life
I am not yet young enough to know everything.
Knowledge is measured by degrees of ignorance.
Absorb what is useful, Discard what is not, Add what is uniquely your own.
If money is your hope for independence you will never have it. The only real security that a man will have in this world is a reserve of knowledge, experience, and ability.
Remember that time is money.
