Who am I?

Rest is as essential
as the water we drink
and the air we breathe
Rest is productive

I am Haulwen Nicholas, a dedicated author and coach, specialising in personality types, energy mindset, and guiding women from exhaustion to empowerment. I live in the magical Welsh borderlands, where I share my home with my husband and two feline health and wellbeing officers, Saffy and Seren.

An introvert by nature, I find solace in solitary moments, allowing me to recharge and harness the inspiration that fuels my passions. Writing, reading, coaching, and sharing wisdom are the threads that weave the tapestry of my life. I see myself as a weaver of knowledge who can transform the complicated into simple strands, as I know how hard it is to process anything when you are exhausted.

For over 25 years, I have dedicated my professional life to environmental sustainability, advising on packaging and its impact on our world. Leading teams ranging from 1 to 25 people, my commitment to positive change extended beyond my professional sphere and to the people in my teams whom I coached. It was my last corporate role that my team members suggested I become a coach, which is where my coaching journey started in 2017.

Burnout after 7 years of holding down a high-level corporate job in the food and drink industry, whilst managing my chronic fatigue, adenomyosis and endometriosis diagnosis, led me to embark on my journey of self-discovery. I founded my business Haulwen Ltd to channel my passions for writing, coaching, and training.


With a degree in Environmental Biology, a Diploma in Packaging Technology, and a Diploma in Aromatherapy and Body Massage. As well as being a qualified Myers Briggs Practitioner, NLP coach, and Time Line Therapy® practitioner, I've honed my skills to set up a successful company that has two distinct strands, that overlap more times than I thought could be possible.


I offer packaging training and advice via my Packaging Oracle services.


My true calling since 2017 though, is for my coaching, writing and training to guide individuals towards personal transformation. During this time, I have developed my own developmental process called The CARIAD Method® to help you find your comfort zone to recharge your batteries and your cosy zone to heal. 


I've also been an Ambassador for Psychologies Magazine and actively helped manage their Psychologies Life Leap Club a group on Facebook. I have also founded The Magical Mojo Academy—a community empowering wise women through journaling, coaching, and support during times of exhaustion.

My expertise has graced the pages of Women and Home Feel Good You, Top Santé, Psychologies, Natural Health, Health and Wellbeing, Soulacy, Spirit & Destiny, and Soul & Spirit magazines. Local newspapers and BBC Radio Shropshire have also shared my insights. My book, "The Book of Personality Tests," even made its mark on Netflix.

Passionate about making coaching accessible, I offer affordable options through books, online memberships, and coaching programs, and my free Facebook group and online resources.


I do offer 1:1 coaching on request to a limited amount of people each year. I occasionally host day and weekend retreats to help women go from empowered to exhausted. I regularly work with my local bookshop Booka in Oswestry to do talks on my current book and personal development in general.


I now offer talks and interviews on the exhaustion epidemic and how to manage it, as well as speaking out about living with chronic fatigue, endometriosis, adenomyosis, and perimenopause. 


I desire to extend my talks to organisations and businesses, guiding them in supporting their exhausted workforces through challenging times.
