Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

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

Quality is not an act, it is a habit.

The wise does at once what the fool does at last.

It's always too early to quit.

Begin to be now what you will be hereafter.

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

You never know what motivates you.
