While there is truth in what you say I can only quote (or rather paraphrase from memory) Michael Mcintyre: have you ever noticed with ATM's, you go up to it and it says "no, I have no money for you, go away". So, like a good citizen you turn round to the man behind you in the queue and say "it is out of money". And he says "thank you.....", and then steps up to try for himself anyway. "thanks, but I don't believe you, it will work for me". So, no, you don't have to "learn things the hard way". But most people nod sagely when you give them advice and then do it anyway :) (and that is a good thing IMO) (I agree with your track records thing; it's too easy to imagine you are giving a "last chance" and that it will really work out this time).
