First let me say I totally agree with Steve and admire his accomplishments as founder of his own venture. Now that Steve has set the table I would like to provide a suggestion on how businesses owners can gather the intelligence required to make those good business decisions Steve has written about.
Be mindful of sector specific and industry specific indexes and indicators that are relevant to your business, for example if you are in the home building industry you can follow the monthly permits and construction and prices indexes which you can find in a web search, if you are in a different industry you just search for things germane to you.
Now let's remember that many indexes are national and some are by state, and some are by other geographical regions so make sure you study the details.
Finally, I want to suggest that you use two or three series of indexes or indicators and make your own decisions based on more then one producer of data, you can make a folder in your bookmarks and have the links of all you indexes, this makes it easy to view the updated data on a weekly or monthly basis.
All this is just a small part of gathering intelligence for making good business decisions.
