We need to steer clear of this poverty of ambition, where people want to drive fancy cars and wear nice clothes and live in nice apartments but don't want to work hard to accomplish these things. Everyone should try to realize their full potential.
Look not mournfully into the past, it comes not back again. Wisely improve the present, it is thine. Go forth to meet the shadowy future without fear and with a manly heart.
Disciplining yourself to do what you know is right and important, although difficult, is the highroad to pride, self-esteem, and personal satisfaction.
