I can, therefore I am.

Either you run the day or the day runs you.

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

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

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.
