Three habits from people who spend money for a living, pointed at your portfolio.
First: they never fund anything without writing down what "working" looks like — a specific, measurable result — before the money leaves. No metric, no spend.
Second: they review coldly. When the numbers say a thing isn't earning its keep, they cut it, even when they liked it, even when cutting stings. Attachment is not evidence.
Third: they build the review once as a repeatable process, so the next decision runs on the same rails instead of on mood.
Most investors do the opposite. They buy on a feeling, then invent reasons to keep holding because selling feels like admitting a mistake. That's not conviction — that's just avoiding a review.
So before your next buy, write the one number that would tell you you were wrong. Then honor it.
What number would make you sell something you currently love holding?
