"We didn't sleep last week - we literally didn't sleep - because we've been so busy with the book"

Hansie Cronje's quote is a testament to the effort and dedication he and his group put into their project. It implies that they worked relentlessly for a whole week without any rest, which is an impressive task. This quote likewise speaks to the importance of the task, as it was so important to them that they were willing to sacrifice their sleep in order to finish it. It is a tip that effort and commitment can lead to fantastic success, which often it is needed to make sacrifices in order to achieve our goals. It is also a pointer that we need to not take our health and wellness for given, which we should look after ourselves even when we are busy.
