What's the best advice you have been given?

My Boss ask me this question last Monday morning. I think I'm up for a promotion so it's part of the drill. Well he caught me off guard. I stumble out something seriously awful & cliche like: "my mum taught me the importance of passion & hard work". Then I went on about how lucky I was to have incredible family , like my parents as my role model. I sum it up by saying" the best advice I've ever received was from my mum: "Whatever you do, do it well."

Hmmm.... he seemed please enough & said that's wonderful! And guess what? Today I got the promotion ! So happy !!!

But I like this better, but it might not get me the promotion though ..haha...
