A psychology expert's top advice on utilizing your fear of death to enhance your life.

How often do you think about death?

Facing one's fear of death head-on is necessary for living a more fulfilling life, according to a psychology expert, despite the pain and grimness of the thought of no longer existing being too much for many to bear and often avoided.

"Jodi Wellman, founder of Four Thousand Mondays, advised CNBC Make It to focus on "mortality math" instead of just money. She said, "Most people focus on their finances, but let's also consider how many Mondays we have left.""

Recently, Wellman, who holds a Master's degree in applied positive psychology from the University of Pennsylvania, published a book titled "You Only Die Once" that aims to assist individuals in reigniting their passion and curiosity for life.

Using a calculator on her website, she advises people to check how many Mondays they have left in their life, as the average person experiences an average of 4,000 Mondays.

The scarcity of time motivates individuals to act in their lives.

According to Wellman, we place a higher value on temporary assets than on infinite ones due to the concept of temporal scarcity.

To avoid being inactive and languishing, we must become aware of the transient nature of our lives, she cautioned.

"Later is an elusive time that may never come," Wellman said. To avoid missing out on our passions, we should remember the limited time we have left.

What would you wish you had done if you were going to die tonight? Perhaps there's an opportunity to start that today, she suggested.

'Mortality can be a motivator'

For many years, the idea that "mortality can be a motivator" has inspired Wellman.

"The paradox of working hard to achieve and love our lives, despite knowing our finitude, has always intrigued me."

Her mother's death at the age of 58 was a key moment that motivated Wellman to explore the topic.

"She died with regrets about unexplored business ideas, unfinished books, unsubmitted stories, and dormant dreams, which was a heartbreaking sight."

For Wellman, the realization that anyone could die early but that it might be preventable to die without regrets was a "visceral wake-up call."

"We can utilize the realization that our existence is temporary to motivate us to live fully and not dwell on it."
