I can, therefore I am.
What you do today can improve all your tomorrows.
To know oneself, one should assert oneself.
The most effective way to do it, is to do it.
You never know what motivates you.
Never complain and never explain.
It's always too early to quit.
If you can dream it, you can do it.
Well done is better than well said.
Be gentle to all and stern with yourself.
The world is my country, science is my religion.
