Psychologists and workplace experts suggest that the happiest people frequently use these three phrases.

Finland and Denmark have seemingly cracked the code to living a happy life.

For seven years in a row, Finland has held the top spot on the World Happiness Report's annual ranking of the happiest countries in the world, which was most recently published in March.

A group of Finnish and Danish business leaders and psychologists were asked by CNBC Make It to explain the results. Some of them mentioned popular sayings that help them maintain a positive and optimistic mindset, even during challenging times.

Experts suggest adding these three phrases to your vocabulary to live a happier life.

'Whatever you leave behind, you will find in front of you'

Facing obstacles directly can prevent their recurrence.

According to Anni Hallila, head of people and culture at Finnish manufacturing company Framery, the phrase "Whatever you leave behind, you will find in front of you" is commonly used in Finland to convey that neglecting an issue will only lead to a larger problem.

Mastering communication and public speaking is the ultimate guide.

If your friend makes a distasteful joke about you, not addressing it immediately could give off the impression that it's acceptable to make similar jokes in the future.

"Hallila advised Make It earlier this month that leaving problems behind will only lead to finding them in front of you. Therefore, the only way to handle them is to address them when they are brought up."

'Pyt med det'

A 2022 poll from the American Psychological Association reveals that over 25% of Americans experience stress that negatively impacts their mental health and productivity, frequently due to concerns beyond their control.

According to Meik Wiking, CEO of the Happiness Research Institute, people in Denmark use the three-word phrase "Pyt med det" every day to get ahead.

In April, Wiking wrote for CNBC Make It that the phrase "It doesn't matter" or "Don't worry about it" conveys a deep sense of acceptance and release of concern. It is a calming reminder that things will turn out okay, even when they appear to be going wrong.

Using the phrase "find happiness" can help you move on from life's ebbs and setbacks, according to Wiking.

""Shrugging off negativity and moving forward with grace and resilience is a good reminder not to sweat the small stuff," he added."

'Some have happiness, everyone has summer'

It's easy to feel self-conscious or envious when you see other people sharing only their best moments on social media. However, happy people recognize that everyone has bad days, and there's "no point" in comparing themselves to others, even when they're struggling, according to Finland psychologist Frank Martela, who wrote for Make It in March.

Despite any challenges, better days will come, as Finnish people often say with the century-old phrase "Some have happiness, everyone has summer."

"Sometimes life gives, sometimes it takes," Martela wrote. "Tomorrow, someone else might be the one going through a tough time, while something delightful comes your way."

"No matter the situation, we can always count on one thing: summer will come to us all," he added.
