Given the title of my blog, it would be remiss of me not to link to a post at Pick the Brain titled 78 Timeless Wealth Building Tips from Benjamin Franklin.
Benjamin Franklin is perhaps the greatest Renaissance Man after da Vinci. Franklin did it all from business, to science, to music to politics.
I have read a few books about him, even an old copy of his autobiography, but I have found the Edmund S. Morgan (Yale History Emeritus Professor) the best one that I have read, and it is worth the effort to get.
The 78 tips, are common sense, and aren't quick fixes, but you can inately see how they would work.
