If they're going to live by that maxim then they need to be consistent... 'You have not won until you sell or realise your gain.'
But do they ever say that? No.

Your failing investments are not hidden away 'in the bottom drawer' - they are in your trading account. Every time you open it, there they are. Reminding you of what you 'haven't lost'.
