Poker Psychology

Something that interests me is how ones outlook can change depending on the game or site one is playing.

I say this because I have had a lot of success on a new poker site (Mansion), and as a result when I am playing on that site I make my plays full of confidence, and seem unaffected by the beats that I suffer. The ability to confidently make the right decision should be one which is learnt and should stay inside you, but I'm finding that mental scars run deeper than I realise, as I can be in two identical situations on two different sites, and the fact remains that one site I play correctly, and on the other I play incorrectly, or badly, purely because I know that I have been 'hurt' by a site (or in this case a network) far too often, and badly.

I suppose the solution would be to walk away from the network until the wounds have healed, but that almost seems like admitting defeat, which I'm not prepared to do.
