Want to achieve more without the stress and overwhelm?

As an ambitious person, I inevitably have a lot on my plate. In just 2 years, I went through pretty much every life change you can imagine. I planned our wedding, got married, moved jobs, moved countries, wrote and published a book, completed an MBA, became a father to my baby son and then coped with his sudden serious illness, all whilst working full time. I had to be the lion. I created new habits and thought patterns, and reconnected with my purpose to get sh!t done. I became stronger, a master of time management, productivity and motivation. As a result, my goals got closer. And there was a surprising side-effect: I became happier and more relaxed.

I distilled everything I learned into my 4Cs model, which enables you to overcome any challenge. This book explains the 4Cs and teaches processes, strategies and optimisations to turbocharge your life. This system will help you to achieve more, without any of the stress, overwhelm and fear that often comes with big life changes. Taking yourself to the next level and achieving huge success should be joyful.
