To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
I mean, it's the life lessons that I suppose you learn that nobody gets a free ride and that you do the best you can with the means that you can and try to open yourself to as much knowledge and all that that you can.
