Be gentle to all and stern with yourself.

The dog that trots about finds a bone.

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

Begin to be now what you will be hereafter.

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

Be kind whenever possible. It is always possible.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

You never know what motivates you.
