When I was working full-time in the bike repair trenches, my personal bike or bike "projects" were the last thing I wanted to work on at home.
Everything worked well on my bike, and I did sneak in a little maintenence at lunch or after we closed. But my bike was nothing to write home about looks-wise.
I remember working in different shops and the fixing wasn't usually too difficult, but the constant onslaught of customers asking questions, along the never-ending phone calls made it incredibly stressful at times.
Cooking was a nice destressor on the weekends, as was socializing with friends.
