Have you ever not gotten enough sleep one night and figure, well, you know, I'll make it up on the weekend?

Sure, if you only got, say, two hours of sleep one night, you may want to sleep in a bit the next day, but in the long term, it's really not about the math.

If you are chronically sleep deprived, you will never make up all the hours of sleep you've missed, and you really shouldn't try.

It's about your routine.

And you do that by sticking to a regular sleep schedule as best you can, weekends included.

And that is something you should know.
