What makes people into 'bigging themselves up' without delivering?
I'm constantly thinking "how can I deliver more for the organisation?", whereas I've noticed that some people seem great at telling others what they're planning on doing, but never delivering on those promises.
I'm amazed at the lengths people will go to, in order to make excuses about not delivering. It's like the old joke excuse 'the dog ate my homework'. My ex and I used to say 'random excuse #654' when we just couldn't be bothered, suggesting that we couldn't even be bothered to make up an excuse.
