I've set myself a goal to read one self-development book per month. To make sure I really reflect on what I'm reading I'm going to extract the wisdom from the best business and personal development books and share it with you.

This month I’ve been reading Predictably Irrational: The Hidden Forces That Shape Our Decisions By Dan Ariely

I want to share something with you I came across a couple of years ago but I wish I’d discovered sooner.  It’s an idea that comes from economics but one that also applies to the investment of emotional and mental resources too.
