I’ve always been intrigued by books like “Reminiscences of a stock operator” where trading is based on continually watching a market and developing a “feel” for it.

When coming from Mongoid from an Activerecord background, there are some subtle differences around uniqueness and indexes which can cause hard to debug problems.
There are a multitude of burning things I really need to do now. ShopOfMe is launching a huge new feature in five weeks, inbox zero has become “inbox less than three pages” and having just spoken to the doctors surgery I’ve been going to since I was a child, they’ve advised me I can't have an appointment because I don't exist.
At the start of 2012, my goal was fairly simple, remain solvent for a full year relying only on consulting income while leaving enough time to bootstrap ShopOfMe and InGuide. No-one has yet repossessed the computer I’m writing this on so it’s fair to say I got at least half way there.
