January, 2021 Update

Our net worth climbed to $91,890 and €75,505, an increase of 5.34% and 5.77% respectively. For the first time, our assets grew above $100,000.

Stocks did well, and we had an inflow of cash that obviously more than made up for our spending. I bought another musical instrument, and actually, these numbers include a double charge for which I haven't yet been refunded, so it was a surprisingly good month. We sold something to some friends for a few hundred euros, and at the end of January, I received a bonus as a kind of stimulus due to the pandemic.

Regarding the pandemic, we can't do anything besides order stuff online. We considered buying some plane tickets, but it seems pre-mature at this moment. We can't go to bars, and we can't even have friends over, which often prompts us to spend a lot on groceries. There was none of that this month. Our money went to things, generally, that we can resell later.

We also hit the bonus for an American credit card, which gave us a bunch of very useful points, which we'll eventually use to save money flying back to Germany one day. I value those at 1¢ per point, though the tickets I plan using them on will cost much more than that were I to buy them with cash.

GameStop Thoughts

Since that's the big market news at the moment, I'll say that I'm not participating in this trade. It just isn't my kind of thing. And I generally try to resist this kind of stuff, even if I might end up winning big. My belief is this: the behavior that might make you outrageously rich suddenly is the same kind of behavior that might make you broke suddenly. So I'll stick to my plan, which is doing fine.

I've also watched r/wallstreetbets for a while as a lurker, and while their trade ideas are often really good, there's a time element to them that requires you to be early or not take part at all. However, with the reinforcing peer pressure on the subreddit -- all that talk about "diamond hands" -- it can incentivize the willing latecomers to participate much later than is wise. Just remember, every time you buy, it means someone else is selling.

Anyway, be careful and good luck.

Tracking Cash-Flow with Sankey Diagrams

There's been a trend on the subreddit Data is Beautiful to display one's monthly cash flow as a Sankey diagram. There were a few days last week where the whole sub was covered in these cash-flow diagrams from different locations, and it was enlightening.

The Sankey visualization helps show the transformation of inputs into outputs, and so it's a terrific way to see how income transforms into expenses. You can build your own here:

I did my first draft of one. It's not for my monthly spending but everything we've spent so far this year:

I'll have to update it once the year is over, and maybe I'll average things out to figure out some kind of monthly flow. As it is, we face expected but one-off large expenses at various points in the year, so I tend to think of them as yearly expenses, and that doesn't jive with a monthly cash flow chart.

A few easy takeaways:

• The "Other Spending" category holds a lot of stuff, but the main sub-categories within it have drastically different weights. Thankfully, the "Household" (those one-off expenses that my wife and I agree to purchase, such as furniture) and "Dentist" categories should substantially drop after this year. As long as we don't spend that money elsewhere that is...
• The smaller expenses are really very small. Compared to the rent, the "Gym" expense is peanuts. I think we should be careful with smaller expenses, but it really does help visualize just how important getting the big things right really is.
• The BLOW categories are surprisingly large. They also contain a lot of different kinds of expenses, and I'm half tempted to break BLOW down into subcategories just to see where that money is going. BLOW, if you'll recall, is sort of our allowances to ourselves to spend on whatever without needing permission from the other spouse. Restaurant bills fall under BLOW, which is why they're not broken out.
• Not having a car saves us a lot. I'd love to lower our "Transportation" costs even further, but, man, this is so much better than when I was driving around in the USA.
• On my next draft, I'll need to add in my automatic withholdings from my paycheck. I'd like to see how that adds up. As is, you're seeing Job 1 as post withholding, and Job 2 as pre-tax. The "German Taxes" and "Rentenversicherung" are only for our estimated tax pre-payments and my wife's payments to the social security system since she's freelance.
