I can, therefore I am.

To know oneself, one should assert oneself.

Only the educated are free.

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

Do not weep do not wax indignant. Understand.

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

The most effective way to do it, is to do it.

It's always too early to quit.

Be gentle to all and stern with yourself.
