People think investing is about the huge decisions.

Should I buy this company? Should I own more of that company? Will AI change the economy?

Those decisions matter.

But your wealth will also be determined by hundreds of smaller decisions that barely seem important at the time.

Did you invest this month?

Did you chase a stock after it exploded?

Did you panic during a correction?

Did you buy more simply because something became cheaper?

Did you check whether the business actually improved?

One decision usually means very little.

Repeat the same decision for 20 years and suddenly it means everything.

Everybody loves talking about compounding returns. Very few people talk about compounding behavior.

Good habits compound.

Bad habits compound too.
