The Duke of Sussex said he now has an understanding of his “value” and has regained confidence.
He shared his experience while speaking as chief impact officer at professional coaching and mental health firm BetterUp.
Prince Harry joined BetterUp’s chief executive Alexi Robichaux for an onstage chat at the inaugural Masters of Scale Summit in San Francisco.
The conference's website said it aimed to “immerse the most forward-thinking, fast-scaling business leaders in an environment designed to cultivate innovation, acceleration and co-elevation”.

During a 20-minute discussion, Prince Harry and Mr Robichaux shared first-hand stories about personal transformation and how to bring positive behaviour change to an organisation at scale.
“The moment I started doing therapy, it opened my eyes,” Prince Harry said.
“I was moving through life thinking there was only one way to live and therapy burst that bubble.
“Then, when I found my way to coaching, the next bubble burst, and all of a sudden I realised that now I have perspective and a great understanding of my value.
“I regained confidence that I never thought I had.”

He said it was “exciting” to know the human potential of every person in the room and across the globe.
“But we’re also at a point where we actually need to unlock that potential. The only way we can do that is to individually grow ourselves, but also help the people we are responsible for grow as well,” he added.
“If you are going to scale your company, the only way I believe you can do that is to successfully scale yourself and scale your employees at the same time.”
