The truth is, success often occurs for reasons we don't expect, under circumstances over which we have little control and sometimes unrelated to our own efforts. There is only one other lesson that success should teach us: Be as amazed by your own success as your friends are. If you truly are, you stand the best chance to repeat it.
A character standard is far more important than even a gold standard. The success of all economic systems is still dependent upon both righteous leaders and righteous people. In the last analysis, our national future depends upon our national character that is, whether it is spiritually or materially minded.
