It is not the man who has too little who is poor, but the one who hankers after more.
Through hardship to the stars.
Men who have made these discoveries before us are not our masters, but our guides.
It is indeed foolish to be unhappy now because you may be unhappy at some future time.
True happiness is to enjoy the present, without anxious dependence upon the future.
Make the best use of what is in your power, and take the rest as it happens.
