It's always too early to quit.

Only the educated are free.

Begin to be now what you will be hereafter.

The dog that trots about finds a bone.

Know or listen to those who know.

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

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

To know oneself, one should assert oneself.

Be kind whenever possible. It is always possible.
