We’ve all heard that we have to learn from our mistakes, but I think it’s more important to learn from successes. If you learn only from your mistakes, you are inclined to learn only errors. Norman Vincent PealeWe've all had the experience of throwing an object and have in miraculously land exactly where you wanted it to. Maybe this happened to you while playing sports as a kid. You threw the basketball absent-mindedly towards the basket and.... SWISH! You scarcely have the time to let the moment sink in and one of your friends turns to you and says, "I'll bet you couldn't do that again!". What about your marketing? Do you truly understand the forces that are bringing your business from day to day? What did you do last year that is putting money in your bank account today? You might feel it is impossible to know for sure. It only takes a little presence of mind and thought to make your marketing efforts more scientific. Starting a marketing diary and keeping track of what you did can start to give you a sense of the cause-and-effect over the course of your calendar year. You don't have to do this perfectly. Any amount of measurement and logging is going to be better than none at all. I would suggest using Google Sheets to track your diary. This will let you easily modify the structure of your diary easily as the need arises. You will also be able to share it with others in your business so they can contribute to the overall picture.
