Context : Here the writer says that we are the maker of our own fate which depends upon our thoughts. We should cultivate good thoughts which will bring untold happiness in our life. Bad thoughts are the source of discomfort and disturbed sleep. So we should avoid them.
Explanation : In these lines the writer says that you are the independent maker of your fate, no matter it is good or bad. The influences which you are sending forth every moment will either make your life or will destroy it. So, for making permanent influence and for getting success in life, you should have a broad outlook and loving and unselfish behaviour with all. In doing so you should not think of money. You may get little money. But your influence and success will surely be great and permanent. Contrary to it you become narrowminded, selfish and unloving, you may earn a lot of money but your influence will be negligible. Thus for getting a good personality and everlasting influence you should not be money-minded.
