Thanks Surya for your kind words and even more so for your astute comment.

With regards to the "informing" characteristic, I proposed that a good decision should allow you to understand yourself more and also understand the world around you more. Let me try to illustrate this point with an example: With regards to financial investing, I recently moved from being mutual funds heavy to individual stocks heavy. This was a big move for me because until recently I used to rather strongly believe that investing in direct stocks is akin to gambling and hence I used to participate in the equity markets only via highly diversified mutual funds. After a careful and a thorough-ish study did I change my beliefs. The fact that I had to deal with my own fears and make a such a consequential move in my life made me realize that I am capable of backing myself up once I put in required due diligence. I understood something about me. I also understood how to structure my portfolio to mitigate the risk of total (or significant) ruin. I learnt something about the world too!

With regards to the role of luck (good or bad) in decision making, I do have plans to write on how dynamism in the world affects our decision making and what can we do to tame this randomness. It will be out in the next 2 or three weeks.
