It's always too early to quit.

Either you run the day or the day runs you.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

Be thine own palace, or the world's thy jail.

You never know what motivates you.

Well done is better than well said.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.
