You never know what motivates you.
Wherever you are - be all there.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.
