Be gentle to all and stern with yourself.

Always desire to learn something useful.

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

Be kind whenever possible. It is always possible.

Begin to be now what you will be hereafter.

Know or listen to those who know.

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

The dog that trots about finds a bone.

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