Never complain and never explain.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
You never know what motivates you.
I can, therefore I am.
Only the educated are free.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Man is a genius when he is dreaming.
