Management guru Clayton M. Christensen died this week . Sadly, he was only 67 (leukaemia). A professor at Harvard Business School, Christensen was best known for probably two things: His work on disruptive innovation and his teachings on how to live a more fulfilling life. If you've read anything on innovation and disruption, I am sure you've come across the work of Christensen. He had a way of explaining things by reframing them. Here is a short video about the "job" of a McDonald's milkshake. And here is another one where he explains the cycle of disruptive innovations, sustaining innovations, and efficiency innovations. Both videos are worth watching.

Feargus O’Sullivan's CityLab series on European housing typologies started in London, but has since gone on to cover Berlin's mid-rise tenements -- called Mietskasernen -- and Amsterdam's canal houses . The series is exactly the sort of thing that I like to geek out about. In fact, I can see a book on this topic staring at me from my bookshelf.

If you end up taking the time to read the articles, you'll be reminded of a couple of things about the way cities work. One, the way we use buildings changes over time. Two, the kind of architecture we pursue is always a reflection of the socioeconomic milieu at that particular moment in time. And three, the way we perceive buildings also changes over time.

In the case of Amsterdam's canal houses, their original function was live/work. They were residences, but they were also warehouses. Amsterdam's maritime dominance meant that it was more profitable to store things, instead of just house people. (Sometimes as much as half of the house was dedicated to storage.) Trade patterns had moved from the Mediterranean up to the North Atlantic, and that worked out pretty well for the Dutch in the 17th century.

In the case of Berlin, their typical mid-rise "rental barracks" went from reviled to coveted as the buildings aged, elevators made the penthouses desirable, and people started to appreciate some of their idiosyncrasies. It's an example of what I was getting at when I spoke to the CBC for this article about Toronto's skyscraper boom. Some things, including buildings, take time. They need to settle in.

One of the most important rules in personal finance is that you should live within your means. Sure you might be stretching to invest or start a business but, generally speaking, people who specialize in this sort of thing (which is not me) will tell you that it's probably a good idea to spend less than you make.

The same is, of course, true in business. Businesses generally try to make more money than they spend. Similar to what might happen in personal finance, there are instances where a company might decide to forgo current cash flow for future cash flow. i.e. Invest in future growth. But at some point, not making any money needs to stop and the company will need to post a profit.

All of this probably sounds dreadfully obvious, but I often think of this very simple principle whenever I hear someone talking about something that should be done, but isn't being done. Developers should be using triple glazed windows in all of their projects. The government needs to build a new subway line from here to over here. And the list goes on.

There's no question that triple glazed windows will perform better than double glazed windows. And there's no question that a subway right outside of my single family home would be pretty darn convenient for my personal needs. But all of these things, unfortunately, cost money. They are expenses. And unless the revenues are there to support them, they, funny enough, tend not to happen.

The same is true in personal finance. I should have a yacht in the Mediterranean. Why? Because having a yacht in the Mediterranean is typically better than not having a yacht in the Mediterranean. Sadly, the top line of my income statement tells me to, instead, focus my attention on the Toronto Island Ferry Docks.

Update: One of our engineers has advised me that triple glazing is not always better from a noise control standpoint. Laminated and heavier glass typically performs better from this perspective.
