Looking back, I can see that I was always proactive and had a strong work ethic. My last book, written when I was in my early 30s, was about the journey of eating well to cleanse and heal. Now in my late 30s, I can reflect that the last few years have been the most challenging, yet most satisfying, of my life. I left my career in magazine publishing, moved country, had a baby and, several months later, started Plenish.

I moved to the UK to be with my husband a month after we married, leaving my home and job in New York behind me. During my 11-year career at Cond Nast, I worked around the clock and had the opportunity to express my creativity and hone my business skills. We did great work and were rewarded for it with upward motion. It was a busy but fulfilling career that I took a lot of pride in, and I suddenly felt a huge void without it. I hadnt realized how much being on a journey fulfilled me. Without it, I felt as though I was standing still, and I didnt enjoy the feeling.

I freelanced as a stopgap while I explored my career options and enrolled in some cooking classes to meet people and make delicious food (some of my favourite activities). I spent a lot of time looking for ingredients, talking to growers at the farmers markets (hey, this is what you do when you arrive in a country with no family, no friends and no job!) and learning a lot about the processes behind many of the products we buy off the supermarket shelves. I wasnt impressed. Being an avid juicer, I was also very frustrated that I couldnt find the organic, cold-pressed juice that I had grown to depend on in the US, so I started creating my own. My new friend Romi (another expat I had recently met in a post-natal yoga class), a talented dietician, was in a similar situation to me, and worked with me to create a range of juices that were not only delicious, but nutrient dense and low in natural sugar. We worked exclusively with growers who followed organic growing procedures (which reduce the exposure to pesticides and promote healthy soils).

A few weeks had gone by, and I was buzzing partly because of all of the cold-pressed juices I was drinking, but mostly because I felt inspired by what we were creating. I started making juices for people I worked with, friends in my yoga class, and asking people for their feedback on how the juices made them feel. The feedback was wildly positive. Not only was I able to be creative, but I also found a way to make people feel good while following sustainable and ethical practices, and it awakened a passion and drive in me that I hadnt experienced before. I felt awake and like I needed to run.

Plenish was born from my own healing experiences via juice and plant-based food, and from my passion for sharing these nutrient-dense recipes so others can feel great, too. I was frustrated with the lack of integrity in most products on the supermarket shelves and I wanted to do something about it.

Since founding Plenish and finding a way to harness that passion and ambition, Ive never been more clear on what we are PRO...

PRO revolutionizing the way we make and distribute food without preservatives and sugars. PRO supporting farmers who grow our organic produce without the use of harmful pesticides. PRO educating people on investing in wellness, not illness, and PRO building a brand that is a platform to inspire and influence real change.

As a brand we never stand still: we relish moving forward, because if youre not moving, youre not growing. Finally, we will continue to challenge ourselves to over-deliver on health and quality and make it more accessible.

Plenish has given me the opportunity to meet some amazing creators and entrepreneurs. A common theme among these ambitious people is that they have more passion and ideas than they do time. They rely heavily on diet and lifestyle choices so they can squeeze it all in. We will peek into the lives of some of these , who will inspire you (as they do me) to dream big and reach for the stars.

I am ambitious and I like ambitious people. Would you feel comfortable saying that out loud at work or in front of your friends?

Traditionally, ambition has had a negative connotation, particularly when applied to women. Ambition is often associated with being ruthless or narcissistic instead of being celebrated as having an insatiable drive to achieve.

Ambition is also commonly associated with financial reward, which for most successful people just isnt the whole story. When I was working an 18-hour shift in a juicing kitchen, it wasnt the idea of financial reward that kept me going; it was knowing there was a consumer who was going to have a positive experience with a juice or a cleanse that pushed me forward. When our first Harvey Nichols order came in, my kitchen manager called in sick and I worked through the night to fulfil it. The buyer gave me a once-in-a-lifetime shot and there was no way I wasnt going to deliver a perfect product. Do I want to have a profitable business that employs talented people? Sure. Is that the only driver? No way.

Channelling ambition into success demands extraordinary self-belief, determination (bordering on the obsessive) and often the courage to risk family and home when it comes to decision-making. Mostly, it requires a ton of hard work. So how do you fuel that ambition and turn it into a successful driver?
