Hard work really pays off I can't just easily forget a saying that states, too many rest, sleep so shall thy poverty increase and to the best of my knowledge a poor man can't be happy because he will be handicapped of almost everything that makes a man happy, hence the need to strive hard in order to make money in life remember money answereth all things including a happy home.
On the other hand it's behooveful to note that you ought to balance work and rest to avoid body breakdown because health is wealth.
