Importance Of Understanding Biological Prime Time

Share On Social Media

When is your biological peak? AND, most importantly, WHY DOES IT MAKE A DIFFERENCE?

During my talks with customers, we usually talk about what time of day they feel most comfortable working on “thought taxing” projects. Are they early birds, night owls, or somewhere in between? In his book Work the System, Sam Carpenter says that your Biological Prime Time is when your energy and focus are at their peak.

Clients frequently state that they have no notion when they are at their peak during the day. However, as they began to pay attention, they discovered that it is easier to concentrate at certain times of the day. Having this knowledge enables people to modify their daily schedule so that things requiring more concentration can be planned during the times of day when they find it easier to concentrate.

Doesn’t that make sense? You would generate a better product in less time if you worked on your most difficult and critical chores during the period of the day when you are at your best!

REMEMBER – Increasing your capacity to work less and achieve more is all about improving your ability to focus, increasing your energy levels, and employing effective time management tactics.

But what happens when you have NO IDEA when you have the most attention and energy during the day? Here’s a little experiment for you to try. Chris Bailey, author of The Productivity Project, suggests keeping track of your energy levels throughout the day. This is his step-by-step procedure.

Estimated completion time: one minute per hour for a week (when you are awake)

What you will learn: You will develop an understanding of how well you manage your energy, attention, and time.

NOTE: If you want to genuinely monitor your body’s natural rhythms, you should abstain from stimulants before beginning this experiment (caffeine, alcohol, sugar). Eat modest, frequent meals throughout the day to keep your blood sugar stable during the trial.


Each hour, on the hour, write down how much energy you have on a scale of 1 to 10, what you’re doing, and the approximate number of minutes you procrastinated in the previous hour.

After completing this experiment for a week, you will be able to determine when your energy and focus are at their peak. Yes, I realise it’s time-consuming, but the end effect is well worth it! (FYI – when your focus is low, the amount of time you spend procrastinating increases.)

With this information, you can plan your day so that your BPT is only used for the most critical projects and tasks. Here’s what I discovered: my BPT hours are 7 – 9 a.m. and 5 – 7 p.m. What about you? Try this experiment and report back!

If you’ve been with me for a while, you’re aware that there are only 168 hours in a week. The exercise above will assist you in making the most of that time – and here’s another tool to assist you in doing so. My Magic 168 Action Guide will assist you in becoming more aware of where you spend your time so that you can be more productive!
