One of the key recommendations of a lot of self-help books describing successful people is that ‘successful people wake up early’. It is for example, a key approach of Robin Sharma and of a lot of entrepreneurs. In this Quartz paper ‘Waking up early won’t change your life—but it’s awesome for capitalism‘, this assumption is examined and is not found to be particularly relevant.
We learn there that this waking up myth is so widespread and deeply engrained that some people take it so extreme that they wake up at 2:30 in the morning!
The paper makes the point that “the cult of early rising seems to miss a pretty obvious point: There is an opportunity cost involved“. Basically, it is linked to spend a larger proportion of one’s waking hours doing work: this includes not having long evenings to do alternate activities, and starting earlier to work and be productive (before the lazy ones wake up presumably, so that we won’t be interrupted).
It seems to me that the issue is to find some time without interruption to be more effective. It can be early or late, depending on one’s own rhythm. But at the end of the day we still need our night’s sleep to be productive. As the paper recommends, the best is simply to have such a rhythm that we don’t need an alarm to wake up!
