I can, therefore I am.

If you can dream it, you can do it.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

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

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

Know or listen to those who know.

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