Never complain and never explain.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
If you've got a talent, protect it.
Either you run the day or the day runs you.
Well done is better than well said.
Only the educated are free.
Wherever you are - be all there.
Know or listen to those who know.
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.
