Written in 1908, and if one internalizes that, this must have been superbly modern at that time. And it's mindset would even be very modern in 2018. Entrepreneurship and working for someone else, technology and people, finding what you can put up in a job with and when it is time to change. Beautifully observant, often hilarious, and also describes the kind of nostalgia one can feel for the present/recent past (as opposed to long gone things) that I'm way too familiar with.
