Without hard work, nothing grows but weeds.

It's always too early to quit.

Go for it now. The future is promised to no one.

Well done is better than well said.

Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.
