Today, I basically ran out of time writing some software - ran out of tine in as much as it had a bug which I couldn't find or fix. Somebody tried to help and I defensively said that I'd spend a little more time working in my code to sort it out... I soon gave in and he's suggestion worked within moments - I was not expecting that.

Then I heard a tweet from @PhilipMcCluskey saying when in doubt, choose humility. Fair play.
