It is popular in today's world to believe that the ends justify the means. We are taught that we have "to play the game" to get ahead. One must have a positive mental attitude. Look at the bookstores, brimming with self-help tomes. You could fill your house with words on how to achieve success.
Unfortunately, when people get that success, they find it is hollow. An astonishing number of million dollar lottery winners are broke within a few years.
So, what can we do to make our lives meaningful? I am not going to tell you to volunteer to help Africa, get religion or join a 12 step program. Those are noble. But no. I am going to tell you to behave everyday with integrity. Be patient. Treat everyone as you want to be treated. (Where have you heard that before?) I may lose financially today. But I am at peace. I'll gain riches tomorrow.
