The Duke of Sussex, who took five months off work when his daughter Lilibet Diana was born in June, said his various work commitments can leave him feeling burnt out, The Sun reports.

During a virtual panel for the US firm BetterUp, for which Harry is the Chief Impact Officer, he spoke about his own mental health as he argued all companies should give employees time to build on their “mental fitness”.

Speaking from his and Meghan Markle’s $20 million Montecito mansion, Harry said bosses should allocate 15-minute “white space” periods during the day.

“I too experience burnout. And getting to the very end of everything I had. Any fuel I had in the engine, it was like, boom,” Harry said.

“That’s when you’re forced to look inside yourself.

“Mental fitness is the pinnacle. It’s what you’re aiming for. The road towards that can be really bumpy … It’s called inner ‘work’ for a reason.”

The father-of-two, 37, said he encourages himself to meditate for half an hour to 45 minutes every day to keep perspective.

“I know I need to meditate every day … You need to put it into your day diary as a habit otherwise it’s the first thing that drops away,” he said.

“I have now put in about half-an-hour, 45 minutes in the morning when one kid has gone to school and the other is having a nap … it’s like, right, it’s (time) for a workout.

“When bad things happen I think, ‘There’s a lesson here, I’m being schooled by the universe.’

“Next time it happens, I’m going to be more resilient and can see a way around it to achieve the ultimate goal. If you have that perspective, every single bad thing that happens, what you perceive to be bad, can be good.”

Despite his lucrative LA lifestyle, Harry said he can’t always do the things he’d “love to do” because of the “stresses” he faces.

He said he uses visualisation to “turn negatives into positives” – admitting it’s his “superpower”.

“Some days are great, some days are really hard,” he said.

“I’m always kicking myself … ‘If you’d have done this, which you know works for you, you wouldn’t be in this state now.’

“It’s work, but of all the work that’s pulled towards us, it’s the most fulfilling work. Apart from being a dad.”

Harry also teamed up with US tennis champion Serena Williams during the lengthy discussion, in which the multi-Grand Slam winner revealed the pair “always have crazy discussions”, adding they “talk for hours”.

BetterUp is valued at almost $6 billion, with Harry’s role – which he took on in March last year – comprising of product strategy, philanthropy, and public advocacy related to mental health.

His address comes after royal expert Katie Nicholl suggested Harry was deliberately “laying low for now” and “doesn’t want to cause any more upset” to the Queen.

She said Harry had “paused and reflected” on his various interviews over the past year.

“He’s realised how much last year took a toll on his grandmother, and doesn’t want to cause any more upset, so is laying low for now,” she told Closer magazine.

Despite that, the Royal Family will be bracing for Harry’s memoir, due to be released this year.

He promised to give an “accurate and wholly truthful” account of his life, writing as “the man he has become”.
