To know oneself, one should assert oneself.
Who seeks shall find.
The wise does at once what the fool does at last.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
After a storm comes a calm.
Be gentle to all and stern with yourself.
I can, therefore I am.
Know or listen to those who know.
Begin to be now what you will be hereafter.
I would think twice about designing stuff for which there was no need and which didn't endure.
