Morning peak (10 a.m. to 1 p.m.). This is when we tend to be most alert, cheerful and cooperative. It’s a good time for critical and creative thinking, operating tricky machinery, or doing tasks that you are worrying a lot or your priority. If you’re planning to ask for a raise, catch the boss before 1 p.m.
Mid-afternoon dip (1 p.m. to 3 p.m.). During this part of the day, don’t even think about investigating into that boring report. Instead, schedule lunch, or job-related activities that require less attention, like answering e-mail or returning phone calls.
Late-afternoon surge (4 p.m. to 6 p.m.). Use this spell of increased productivity for tasks that demand concentration, such as proofreading, crunching numbers and planning the next day’s agenda.
Early evening second wind (7 p.m. to 9 p.m.). If you feel motivated to work after dinner, it’s a good time to learn new things, read technical journals or study notes for an upcoming presentation. Just be sure you quit within two hours of bedtime or you may have trouble falling asleep.
