you succeed in failing but if the thing you wanted to succeed in was failing failing then you have failed the thing you wanted to succeed in but succeeding in what you wanted to fail so it was a total failure.
A much more interesting question. If Pinocchio says "My nose grows now", what would happen?
"Now" is essentially an instantaneous moment. If Pinocchio's nose can assess time-based lies then it must have some sense of time; let us assume there is a smallest unit of time it can measure. As soon as one of these units of time has passed since Pinocchio made the claim, his nose will grow. That's assuming he was in normal state to begin with. If he says it when his nose is already growing then his nose should continue growing as there's no reason for this truth to cancel out whatever lie he told.
