I manage at least a couple of hours a day commuting to an from London. So if you see a strange clueless geeky looking induhvidual with his head buried in a selection of Bristol notes at Bank station...that's me that is!
Seriously, the two hour train journey is a godsend. So if you drive to work, start taking the train
Frankly, being a geeky bloke I actually find most of this stuff quite fascinating and so far, very relevant. Although I do find that I have to keep revisiting previous chapters or the detail just seems to get forgotten for lack of use.
