Each time we do this, we are contributing to our pile of underpants. Whether it’s scanning a fitness site for advice on completing a marathon, reading a phrase book to better learn French, watching a video of somebody doing parkour, attending a TEDx conference and learning about volunteering opportunities in Africa, or even just reading this very book, we are all making mental notes of the things we’d like to do. This is the equivalent of collecting a pile of underpants.
