  • Calm your mind. Change your life.

    Do you tend to live in your head? Do you sometimes lie awake at night with anxious, repetitive thoughts? Do you feel you get in your own way? If so, this is for you.


    The Overthinkers' approach offers a unique way to get out of your head and into your life: a life with more aliveness, authenticity, freedom and ease. It's not about positive thinking or trying to control or change what's going on your mind. None of that works, really. Instead, it's about changing your relationship to your thinking, tuning into your body's intelligence, and shifting into a new way of being. If you're open-minded and ready to commit, you can experience transformational benefits pretty quickly.


    I'm Andrew - a coach, author, and the founder of Overthinkers Anonymous. I added 'Anonymous' to the name because I think many of you are suffering in secret. By day, you wear your professional mask. But at night, it's a different story. It's time to change all that.

  • Praise for the book

    'The Overthinker's Guide to Life' is a 28-day guide that's informative, practical and easy on the eye. It's like a Couch to 5K for overthinkers.


    Here's a recent review:


    "Candid, warm, inspirational — I’ve read plenty of self-help stuff over the years and none of it has resonated with me half as much as The Overthinker’s Guide to Life.

    A natural cynic, I’ve always found a lot of self-help to be a little trite. The best thing about this book is how refreshing, honest, and relatable it is.

    Andrew achieves the perfect blend of psychological exploration and actionable advice — he offers a succinct theory of why we might think/feel the way we do, and supports it with simple steps you can take to combat your thinking frenzy.

    It’s divided into daily advice, so you don’t feel overwhelmed if you prefer to put one foot in front of the other. I personally read it all in one go, such is Andrew’s natural, conversational and easy writing style.

    If you ever lay in bed tussling with your million-miles-an-hour thoughts, give this a read. You won’t regret it!"

    Antony Mason

    Technical Operations Leader at GE Healthcare

    "In a year of massive change for me personally and the business as a whole, coaching with Andrew helped keep me sane.


    He supported me, challenged my mindset, and helped me develop clear insight into what I should and could be doing."

    Kenny Fox

    Research Director at

    davies & mckerr

    "I started working with Andrew when the self-critical voice in my head suddenly found a megaphone.

    Andrew made me realise that these thoughts were just that, thoughts, and gave me the tools to understand them. I'm without doubt more confident in my job and life, which I put down to working with Andrew."

    Emily Larkin

    Head of Employer Brand

    at the BBC

    "I've worked with Andrew previously as a writer and more recently as a coach. He's provided invaluable support to my overthinking mind, as I navigated a recent career transition and landed in a new role.


    I always leave the sessions with a renewed sense of calm and connection to my instincts. I would recommend to anyone who could benefit from a regular break from a busy head, in a relaxed, grounded, and entirely non-judgemental space."

    Chloe Fowler

    Founder at The Nest Research

    "I started working with Andrew as I made the decision to step down from owning a successful research agency and go it alone.


    My sessions were so helpful. Andrew shifted his style to suit my needs – from coach, to mentor, to creative collaborator, to cheerleader, to kind critic. I've gone from being clueless to having a brand, a vision, a website, a strategy. Ultimately, he's helped with the thing I needed to discover the most – my story."

    Sanjay Mitra

    Corporate Partnerships Manager

    at Speech and Language UK

    "I can wholeheartedly say that I feel much better equipped to meet my work challenges, and more confident in meetings and presentations. I am now finding ways to bring more of my authentic voice to the table."

    Tom Anderson

    Managing Partner at davies & mckerr

    "After a successful, but frantic few years, and facing a major moment in my career, I got in touch with Andrew with the aim of trying to avoid burning out.


    Our conversations together were far more wide ranging. Andrew helped me reframe the way I viewed work, allowing me to identify what is actually important and re-find my excitement for the work I do.


    On top of all that, Andrew is just really sound. He's a fantastic sounding board for ideas and provides a warm, safe environment to discuss topics that might feel uncomfortable in other contexts."


  • About me

    The official bio

    broken image

    Andrew Sewell is a highly experienced leadership & personal coach, and the founder of Overthinkers Anonymous.


    Over the last five years, he has coached clients with senior roles in organisations such as GE Healthcare, John Lewis, Havas, HSBC, Roche, Coles (the Australian supermarket), as well as a range of creative, insight and design agencies.


    Before becoming a coach, Andrew had a wide-ranging career. This included teaching English as a foreign language, scriptwriting in Hollywood, stand-up comedy, as well as many years as an advertising copywriter and creative leader.


    For Andrew, coaching is not a game of coach and client. It’s about two or more intelligent people having an honest conversation. A collaboration of equals. As a thinking partner, Andrew’s main strength is being able to help clients see beyond the blinkers of their own mind. From this new perspective, they have the chance to find their zone of peak performance and feel a greater sense of well-being in their lives.


    Qualifications include MSc Psychology (Distinction), PG Certificate in Business and Personal Coaching, BSc Health Studies, Associate Certified Coach with the International Coaching Federation.


  • Book a test drive

    If you're interested in coaching, the first thing to do is arrange a 1-hour coaching test drive. This gives you the chance to find out more about how coaching can help you, learn about my unique approach, and to see if I'm the right coach for you.


    It also gives me the chance to see if the chemistry is good between us. In my book, chemistry is the most important indicator of successful coaching.


    To set up a coaching test drive, email me at andrew@overthinkers.co.uk Please include a brief note about your current situation.
