Assets vs. liabilities: who feeds who?

Here is the whole idea in one sentence: an asset puts money in your pocket, and a liability takes money out of it.

That is it. The rest of this post is examples, and a couple of jokes about gyms.

The cow and the dog

Imagine a cow. It gives milk every day, you sell the milk, you make money. That is an asset. Now imagine a dog. It eats, it needs a vet, and it sits on your sofa and sheds on your good shirt. That is a liability.

Real life has the same animals, just with fancier names. Watch a normal month sort itself out:

Notice the shape of it. Assets are quiet. They work while you sleep. Liabilities are loud: they send you a bill every month, usually with a friendly email.

It is about what it does, not what it is

The same thing can land on either side. A spare room is a good example:

If you just keep it empty, it only costs money. If you rent it to a student, it makes money. So the question is never "what is this?". It is always "where does the money go?"

A house you live in sits in the gray zone. It can go up in value, but it also eats money every month: taxes, repairs, that one pipe. Be honest about both sides.

The part that is not on the spreadsheet

Now, before you sell your dog: not every liability is a mistake. A trip with friends, a good dinner, the dog itself. By the math they are liabilities. By every other measure they are some of the best things you will ever pay for.

This is an idea we will come back to many times in this series: life is not a spreadsheet. The goal is not to delete every liability. It is to know which is which, so you choose them on purpose.

So, what do I do with this?

One simple habit. Before you buy something, ask: "is this feeding me, or am I feeding it?" Then, when you can, buy a little more of the feeding kind first. A cow before a second dog.

Next up: how much money you need before any of this feels safe. Spoiler: it has a boring name, and the name is "emergency fund".
