It is not good to work all the time , nor it is good to play all the time . When you work , you should work in earnest , and then you will be the more happy when you play . Do one thing at one time , and do it well . If you have any work to do , take hold of it in earnest , and you will soon finish it . If you have a lesson to learn , don't stop no matter how hard it is , but study , and do nothing else , until you have mastered it .
