Even Justin Bieber struggles with work-life balance.

The “Sorry” singer apologized to fans in a lengthy Instagram post for abruptly canceling his “Purpose” World Tour last week detailing that he needed some time off to take care of himself so he could be “sustainable.”

“I want my career to be sustainable, but I also want my mind heart and soul to be sustainable,” he wrote.

“So that I can be the man I want to be, the husband I eventually want to be and the father I want to be.”

And experts say it was probably a good idea he did.

“The way he’s painted in the media makes it sound like he’s partying, staying up late, and probably doesn’t have a structure around his life in order to make sure he’s doing things to keep a certain energy base,” New York based career counselor and life coach John Kalinowski tells Moneyish.

A recent report from Deloitte found that Millennials are placing their personal values and interests ahead of work, and in this instance, Bieber, 23, seems to be doing the same.

And it could pay off for his career in the long run. People who balance a 60 hour work week with hobbies and self-care are typically more productive and emotionally engaged. They are also less likely to burn out.

It’s working for the world’s busiest billionaires who take time to decompress. Oprah Winfrey is known for practicing Transcendental Meditation — a technique for relieving stress and anxiety — twice a day for 20 minutes. Billionaire investor Warren Buffett lets off some steam by playing bridge and his signature ukulele and Virgin founder Richard Branson loves to kite surf.

Sure, we all feel like we don’t have enough time to manage work life with leisure and wellbeing, but Kalinowski says working on one new habit a little bit each day is key.

“We don’t give ourselves enough time to create a habit. If you haven’t done it in three months at least it’s not a habit. It can take months, even years,” he says.

“A habit can be built in small increments. If you want to wake up 30-minutes earlier, start by setting your alarm five minutes earlier, then 10 and work your way up to the goal,” he suggests.

When it comes to the workplace and maintaining a “sustainable career,” the Harvard Business Review says it’s important to start writing down all the ways you add value to your company, employer or your own business. List everything you accomplished at the end of the week, including feedback you received from your boss. This will help you become more self aware. Then you can align your accomplishments with your career goals and discuss them with your boss regularly. And keeping up with developing trends in your industry will help you evolve with it.

It’s also important to know your limits, like Bieber.

“Pull out a calendar and be realistic with yourself by asking, ‘I have this deadline or this thing I want to do. What do I need to do to prepare for it?’ What is reasonable? What’s achievable?” says Kalinowski.

Finding work that suits your preferred lifestyle is also important. Many millennials Bieber’s age are on hunt for career opportunities that offer employees more freedom and flexibility, like working from home, Forbes notes.

“We’re in an age where people are changing careers or having three or four jobs over the course of their lives, changing industries is becoming more and more common,” says Kalinowski.

“A sustainable career is about knowing yourself, figuring out your values and what’s important to make sure you’re in a career that aligns with who you are.”
