I started studying economics in my free time because abstracting how humans behave with math fascinates me and you start to understand what a complex system really is. Markets are very complicated and unpredictable in the short term, but you can understand the atomic unit of the market just fine; a transaction. It’s the same with all complex systems; try to work from the bottom and up, always begin with what you can wrap your head around. After a while, you see that the methodology of building abstract models that are good enough is very similiar in most fields. You discover that it’s never easy and you should always be careful trying to recycle a model by mapping it to an entirely new system.
