"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors."

If you spend too much time thinking about a thing, you’ll never get it done.

We should weep for men at their birth， not at their death.

Your time is limited, don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
