To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

The most effective way to do it, is to do it.

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

Never complain and never explain.

Be kind whenever possible. It is always possible.

Things do not happen. Things are made to happen.

Always desire to learn something useful.

Be gentle to all and stern with yourself.
