If your morning routine has at least one meaningful activity, it's a win. And that "doesn't have to take three hours," Vanderkam said.
If you want to add more exercise, don't feel like you need to go on an hour-long run. Do the seven-minute workout. And while meditating for 30 minutes can be highly-beneficial, so can five minutes of silence.
Also, there's a surprising benefit to being a little sleepy during your morning routine, Barker said. When we're tired, we're "fuzzy" in the head — therefore, more creative. Sort of like "write drunk, edit sober."
"In the morning typically they are going to be more creative and less analytical," Barker told Business Insider. They should ask themselves in the morning, "What are the creative problems that I need to solve first? Not the rigorous, logical tasks."
So perhaps morning might be the best time for night owls to get started on that Pulitzer Prize-winning novel — or just writing a page in a journal for similar mental benefits.
