Being a small businessman (That means having a small business not being under five foot tall) means that there is often a temptation to continually work. Unfortunately I succumb to that temptation, I generally work. One of the places that I often do work is in the car. Now I am not sending e-mails. I am not texting, although I have been known to do it at traffic lights for example. What I tend to do is to listen to podcasts.
Having an iPhone means that I can put the podcast on in the car and from that I can listen to whichever one I want. One of my most listened ones is by Dom Goucher and Pete Williams and is called Preneurcast.
