What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
Who seeks shall find.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
After a storm comes a calm.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Diversity in the world is a basic characteristic of human society, and also the key condition for a lively and dynamic world as we see today.
