"No, when I worked as an accountant I was falling asleep waiting for 5 o'clock"

Heston Blumenthal's quote is a funny method of revealing his frustration with his former job as an accountant. He is indicating that the task was so dull and tiresome that he was actually going to sleep while waiting on completion of the workday. This quote speaks to the uniformity of the task and how it was not stimulating or engaging enough to keep him awake. It also speaks to the significance of discovering a task that is fulfilling and enjoyable, rather than one that is just a means to an end. Blumenthal's quote is a pointer that it is important to discover a task that is significant and engaging, instead of one that is merely a way to make money.
