I know that this is supposed to be a blog about building cities, but it's also a blog about real estate and I have heard that people sometimes do things like invest in real estate. So here is a terrific memo by Howard Marks (of Oaktree Capital Management) about when to sell assets (and when not to sell assets). His overarching argument is that, most of the time, staying invested is ultimately the most important thing. But that it can be difficult to do.

Here's an excerpt:

When you find an investment with the potential to compound over a long period, one of the hardest things is to be patient and maintain your position as long as doing so is warranted based on the prospective return and risk. Investors can easily be moved to sell by news, emotion, the fact that they’ve made a lot of money to date, or the excitement of a new, seemingly more promising idea.

Howard is talking about the stock market and his words of advice are particularly important in that context given how easy it is to be a "trader." I can, so maybe I should. But the same lessons hold true for real estate, even though it is a less liquid asset. A lot of wealth has been generated over the years by those who simply bought well and held for the long term. One good decision and patience can go a long way.

I am sure many of you are getting tired of the news. I know I am. But it turns out that when you're in a global pandemic and you spend the entirety of your day looking at Zoom -- while fidgeting your leg, I might add -- there's only so much else you can talk and write about.

One of the more interesting things you could read is Howard Marks' memos. Howard is the co-founder of Oaktree Capital Management and, from what I can tell, he's been writing since 1990. Some years it's an annual memo and some years -- like this year -- he writes a bunch more. His most recent is regarding, "Knowledge of the Future."

If I had to summarize it: The future is unknowable and none of us can say with any certainty what the next quarter or the next year is going to look like. In Howard's words: "These days everyone has the same data regarding the present and the same ignorance regarding the future."

Most of the time, he explains, we simply extrapolate from the past and then apply our own biases to come up with a prediction. Howard describes himself as more of a worrier, whereas I would describe myself as more of an optimist. I believe, to a certain extent, in creating self-fulfilling prophecies.

Notwithstanding our inability to predict the future (which isn't a new phenomenon), I think it's important to have opinions and take positions. Any decision is better than no decision, right?
