To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.

After a storm comes a calm.
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.
