Creativity: the best time to do everything

In "Your Body's Best Time to Do Everything," The Wall Street Journal provides a little pop psych that I can believe in, more or less.

• 8 a.m. Write upbeat tweets. [No thanks.]
• 9 a.m. High energy and clarity; have difficult talks now. [No thanks. Use that energy ]
• 10 a.m. Do cognitive work. Working memory and concentration tend to peak mid-morning. [Good writing time!] 
• 2 p.m. Take a short nap. Sleepiness hits its peak. [Don't we wish we could all do this?]
• 4 p.m. Do physical work. Eye-hand coordination rises in late afternoon.
• 5 p.m. Work out. Muscle strength and flexibility rises later in the day. 
• 9 p.m. Work creatively. People's freshest, most original thinking may occur at non-peak times of the day, which for most people is evening. Fatigue may lower inhibitions and open the mind to offbeat ideas and solutions. [Finally a research finding that confirms what I've experienced for years.]
