Your brain doesn't work the same all day. About 15% of people peak early (larks), 20% peak late (owls), and the rest follow a peak-trough-recovery pattern. Match your hardest thinking to when you're actually sharp.

One thing we know very clearly is that in the unit of a day, our cognitive abilities don't stay the same throughout the day. That's really important. We have this notion that, okay, our abilities are going to be basically pretty much constant from the time we wake up to the time we go to sleep, and that is not true. Our abilities vary in significant ways. We move through the day in 3 stages: a peak, a trough, a recovery. Up, down, up again. Now, in order to figure out when to do the right thing, you have to ask It's going to answer that very question that you just asked, Brian, which is, what is your chronotype? Are you an early riser? Are you a late riser? Do you wake up early and go to sleep early? Do you wake up late and go to sleep late? Or are you in the middle? 15% of us are larks, early people. 20% of us are owls, late people. And there's some super extreme late people. And then 2/3 of us are in the middle. What you have to do is you have to figure out what your chronotype is. Are either larks or in the middle. Those folks move through the day peak, trough, recovery. Owls, owls are much more complicated. They tend to move through the day recovery, trough, peak, basically have their peak moments later in the day.
