We live in a society where hustle and achievement are coveted metrics for entrepreneurs. But what about effective time management along with recovery and restoration?

After all, the body, much like a vehicle, can only undergo so much usage until the light comes on signaling it's time to refuel. Unfortunately, there are a plethora of entrepreneurs who are disregarding this light and are running themselves into the ground (along with their productivity and time effectiveness).

In actuality though, this behavior is completely unnecessary.

It's no secret that one of the key factors to top performers' success is their ability to manage their time in an efficient and effective way, which, in turn, leads to them producing at higher levels.

One of those top performers is Jeff Bezos who recently shared his philosophy and keys to time management on a column reported by The Wall Street Journal. If you're looking to think and perform better, adopt this one rule.

Prioritize your circadian rhythm

When discussing his habits and routine, Bezos states: "I go to bed early, I get up early, I like to putter in the morning, reading the newspaper, drinking a cup of coffee and eating breakfast with my children."

As he expounded on his reasoning for this, Bezos stated "His primary job each day as a senior executive is to make a small number of high-quality decisions. That means getting eight hours of sleep, too. "I think better, I have more energy, my mood's better.""

Lastly, Bezos schedules "high IQ" meetings before lunch (around 10 a.m.) and attempts to finish making tough decisions by 5 p.m while aiming to make three good decisions daily.

Sleep is important, but Bezos's philosophy described above is going one level deeper than people go when it comes to optimizing their performance. Bezos is aligning his circadian rhythm to what best serves his performance and lifestyle.

Think of sleep as nutrition for your brain. Your circadian rhythm is one of the biological processes that govern sleep in a 24-hour cycle. As you go through the day, you'll experience fluctuations in appetite, blood pressure, body temperature, concentration levels, and fatigue levels.

Optimizing your sleep and schedule lead to more energy, which increases your effectiveness and efficiency. There are certain times of the day where you'll be mentally sharper and these are the times that should be reserved for your toughest of challenges and obstacles.

A well-rested brain makes its best and highest-quality decisions before noon and will be generally tired by 5 p.m. It's tempting to burn the candle at both ends, but prioritizing rest will often times, lead to your biggest breakthroughs and advancements.
