Or that you day-trade index money and the Dow has gone up the past a few times. Considering the fact that you determine matters usually even out, you make a decision the market place will slide currently — no matter of financial fundamentals.
Or, in simple terms, that you have flipped a coin five situations and each and every time it is come up heads.

The key is to imagine substantial quantities as an alternative of compact figures. If you have established, via real details and assessment, that designs do exist — for instance, that it normally takes 100 chilly calls to land 10 prospective buyers — feel about small-phrase final results in that context.
