It's always too early to quit.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

The dog that trots about finds a bone.

After a storm comes a calm.

Be gentle to all and stern with yourself.

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

To know oneself, one should assert oneself.

If you've got a talent, protect it.
