Disasters averted

There's nothing more satisfying than a mistake averted. Like when you realize you missed something on a document that you left on your boss' desk to sign and then manage to print off a corrected copy and put it on their desk before they notice. Or, as happened to me just now, when it looks as though you made a huge mistake in invoicing a client, and your boss is the one who brings it up to you (no chance of fixing it without them knowing!) but then you find their file and along with it the evidence that there was no mistake and everything is according to procedure. PHEW! Relief. Satisfaction.
