I can, therefore I am.

The secret of getting ahead is getting started.

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

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.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.
