ClassPass founder Payal Kadakia, who turned her passion for dance into a billion-dollar business, is sharing secrets to her success in her new book, "LifePass: Drop Your Limits, Rise to Your Potential -- A Groundbreaking Approach to Goal Setting."

Kadakia launched ClassPass, a subscription service that allows users to easily find and attend fitness classes in their area, in 2013, after leaving her corporate job. In her book, she dives into her goal-setting technique, which she has coined "The LifePass Method."

"One of the reasons I started my goal-setting method ... was because I was succeeding in my business life, but not necessarily in my personal life," Kadakia, 39, told ABC News' Shivani Parmar and Zohreen Shah. "I think people sometimes have it the other way around, and I needed a system that was going to help me really focus in on all parts of my life, not just the things that people have told me to always be good at."

Kadakia's four-step, goal-setting method focuses on helping people reflect on their lives, identify their dreams and put themselves back in charge of their priorities.

1. Probe into deep feelings and emotions that define yourself

2. Define what your dreams are

3. Rate the goals and figure out how much time you want to put into that goal

4. Create a plan for those said goals

She recommended focusing on specific, measurable progress through intuition, pie-in-the-sky dreams, micro-focus and macro goals.

In the book, she said, your intuition will tell you if the time is right to meet a specific goal and to listen to the inner voice and figure out what goals you want to focus on.

To guide her readers, she made an easy-to-follow template with a side-by-side view of how Kadakia used the template in her journey, sharing her authentic experiences and feelings.

"I didn't always feel comfortable in who I was and I think over time I really learned to embrace who I was and the different parts of me, instead of living a dual identity, which so many of us face," Kadakia said. "I wanted to bring all parts of me together, whether that was the Indian girl, the American girl, the dancer, the business person."

When it comes to people whose goal is to start their own business, Kadakia, who grew ClassPass out of her lifelong passion for dance, said it is important to love what you do.

"They should know that it's going to be a marathon, not a sprint, that failure is a data point and that they should always remember why they started their company," she said. "I think the heart of it is when you love what you do, you aren't working a day in your life."
