Happiness lies not only in the life of plain living but also in the life of high thinking. So, a saying goes on ‘plain living and high thinking’. If you live a life of high thinking the trifling worldly troubles will not disturb your mind. With your high mindedness and broad heartedness you will be able to excuse your small complaints and thereby you will be free from a lot of troubles. High-mindedness depends on plain living. If you do not be plain in your living you will fall in constant wants and you will become a self-seeker which will lead to low mindedness and meanness. So, in order to live a happy life, you should follow the dictum ‘Plain living and high-thinking’.
