10x ? Very good. You are right, you should've done that.
Telling wife? Bad idea, and a reason for losing. (too complex to explain long)
The difference between a business and trading is that trading is way more scalable and liquid, no comparison.
There are very few exceptions like Amazon, but the exceptions only validates the reality.
So if you step back and find a trading "trap" that works, then you can scale it. Done.
What stays in the way of this is the greed. It brings impatience and breaks the discipline.
But totally doable.
