This learning is the simplest way to remain happy. we must remember that our life is short and, in this short life, we cannot get everything what we want. If we want everything, we will not get happiness. we will get frustrated and we will plunge into the world of sadness. it is always better to be contented with what we have than to live in eternal sadness. we should bear in mind that great men of the world didn’t long for much wealth they remained happy with a little. man can mould his own life worthy he values the necessity of life morally.
