the secret of being miserable is to have the leisure to bother about whether you are happy or not. So don’t bother to think about it! Spit on your hands and get busy. Your blood will start circulating; your mind will start ticking and pretty soon this whole positive upsurge of life in your body will drive worry from your mind. 

    Get busy. Keep busy. It’s the cheapest kind of medicine there is on this earth and one of the best. 

    令自己感到沮喪的秘訣就是用空閑時間去煩惱自己是否快樂。所以不要費事去想它！摩拳擦掌干起來吧。你將熱血沸騰，你會頭腦清醒。很快，在你身體中的這種高漲的積極人生觀將把煩惱從你的頭腦中趕出去。

    行動起來，忙碌起來。這是世界上最便宜的一種藥，也是最好的一種。
