Always desire to learn something useful.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Begin to be now what you will be hereafter.

It's always too early to quit.

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

By failing to prepare, you are preparing to fail.

Quality is not an act, it is a habit.
