I am noted for not

I am noted for not taking good advice. Stuff like “look both ways before crossing the street” or “you really shouldn’t get together with her, it’ll be bad news”. For some time, the advice-that-has-not-been-taken at the head of this site has been:

“If at first you don’t succeed, try, try again. Then quit. No use being a damn fool about it.”
– W.C.Fields

Some advice which I received from Sarah last night was this (with apologies for paraphrasing):

Sometimes it pays to think less and act more. You won’t find out unless you actually do it.

But my favourite newly received advice that I will not take is this:

“Never play cards with a man called Doc. Never eat at a place called Mom’s. Never sleep with a woman whose troubles are worse than your own.”
-Nelson Algren, A Walk On The Wild Side

Do you have any advice not to take?
