In the confrontation between the stream and the rock, the stream always wins not through strength but by perseverance.
Do you always want to be right, or do you want to be happy
Don't be afraid to go out on a limb. That's where the fruit is.
Let the refining and improving of your own life keep you so busy that you have little time to criticize others.
Don't say you don't have enough time. You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michaelangelo, Mother Teresa, Leonardo da Vinci, Thomas Jefferson, and Albert Einstein.
