If you were ever to try meditation, you sound like you might get the most out of Mindfulness in Plain English. The author presents meditation as a practice which serves a philosophy. The philosophy is that as a species we suffer from our emotional attachments to the outcomes of events, to the objects around us, etc. In geek parlance, we have stress responses that were appropriate in our evolutionary environment but are unadaptive to modern life. Meditation is a practice that helps us override these stress responses, and for many people meditation is a better tool than attempting to override those stress responses with thoughts. And even if you don't consider yourself particularly stressed, a Buddhist might suggest that overriding those responses can help remove the weight of attachment from your decision making process and make you into a more rational person.

If you ask how to start a successful business, then I will give you advice on that. If you ask how to stop being a loser, then I will suggest that you are not a loser and you have some depression. In that case, what helped me was getting a diagnosis, reading books on psychological disorders, understanding CBT, and mindfulness meditation/vipassana.
And if you are both depressed and wanting to start a successful business, I suggest that the best place to start is in learning how to deal with your illness.
The fear is that if you train it on FY 2010 and then it does well in a simulation of FY 2010, it might only be because it has stored some representation of a record of FY 2010 which is extremely predictive of FY 2010 but doesn't generalize well to any other year. Testing the algorithm against a simulation of FY 2011 would reveal this flaw.
