To know oneself, one should assert oneself.

Never complain and never explain.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

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

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

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

It's always too early to quit.
