My approach, with all my businesses... depend on automated systems. If I can't find a way to automate business processes with zero humans, I walk away from the money.

At first glance this might seem a costly mistake.

There's a big difference between income + profit.

I focus on profit. If I can automate processes without humans, then a business scales forever.

Also, without humans involved, I know process correctness runs at 100%... and I have no humans, so no overhead expenses, so 100% profit.

My suggestion. Go for automated systems producing 100% profit rather than humans.
