When I switched from construction to freelance web design I spent a couple years doing part time so I could listen to podcasts. Digging, or just about any repetitive physical activity, is therapeutic and unlike programming I don’t have to think much. Now days I do a similar thing with the gym, but it’s still not the same. Reminds me of the end of Office Space where the main character refuses a new programming job because he likes digging and working outside.
