Beware of silver bullets


The areas of personal development, spiritual growth and self help have evolved into a multi-billion-dollar industry, reflecting our deep desire to connect with something more meaningful - to find the healthy peaceful us in our busy lives.

Amongst the vast ocean of options, we’re flooded with hollow gimmicks and unsubstantiated promises, like “60 seconds to transform your life”, or “the 3 steps to everlasting happiness”. 

Where’s the proof any of this works? On the other hand, a number of these supposed silver bullets, that scientists have proven don’t work, keep being sold! It’s no wonder that around 95% of attempts to improve our lives fail! And even if you find something that resonates with you in say a book - how do you make it real in your life?


How iWithin was discovered

I Discovered What Really Works, the Hard Way.

It wasn’t until I reached rock bottom that I found what I was looking for. 

I’ve been very successful in the health and wellbeing industry, starting a number of businesses including a gym and a weight loss centre. I even had a crack at venture capital and starting a stock broking firm branch. But while I enjoyed the material success of my labour, in my 20s I went through a decade of crippling depression and anxiety. 

I was prescribed drugs but wouldn’t take them - I was sure there was a better solution. For me it felt like a crisis of soul and mind rather than a medical issue (although for some this isn’t always the case.) 

I tried everything you can imagine; every type of self help I could find, from Anthony Robbins to herbs to meditation to psychology. I read hundreds of books, and even meditated for 6 to 8 hours a day for months on end with guidance from Buddhist teachers - some who lived with and were taught by the Dalai Lama. I saw psychologists and counsellors.

Finally, some of these great teachers and experts helped me overcome this depression with meditation, mindfulness and scientifically proven techniques.

I really wanted others to have the benefit of what took me a long time and much work to find. I was fascinated by how some people succeed whilst many others don’t. It seems that people who are unsuccessful have a built in immunity to change - and they commonly say that they lack the time and can’t keep up the change. 

So applying the scientific and analytical rigour of my university degrees in biology and law, I spent countless hours studying and trialling Personal Development, Buddhist, Christian, and Hindu material, and researching thousands of scientific papers and experts to find out what really works.

From my exhaustive research I saw a pattern unfolding; a formula, comprised of 21 ingredients that anyone can apply to fulfil their goals. In all of the success stories I studied, either most or all of these 21 ingredients were present. 

Whether it’s for weight loss, sleeping issues, beating depression, reducing stress or finding meaning in life, I’ve seen this formula applied, time after time, consistently helping people achieve the goals that matter most to them. 

I wanted to make sure this was not just theoretical. I practiced and honed what I’d learned; how to turn my busy mind off; how to re-energise myself; how to drop the stress, sleep better and have more confidence. 

Applying this formula helped me to build a highly successful career in one of the hardest professions on the planet – being a partner of a major law firm working on billion-dollar investment deals. I was able to thrive in this high pressure environment while still making time for a life that had real meaning for me with a wonderful wife and children.

It’s not just me the formula has helped: people who couldn’t sleep for 25 years are now able to have a proper night’s rest. Workaholics have achieved balance in their life. People with long term obesity have lost weight without dieting. All of this is based on real science and real results.    All the best, Nathan Cahill



We often resonate with profound ideas but we lack the means to make them real in our lives.

We at iWithin wanted to make a tool to translate this formula for success into a short, daily routine that can be fit into our busy lives. The research shows that small, incremental practices over time can accumulate into profound personal transformation and a meaningful life for the user. Certain practices have even been shown to physically rewire our brains in 8 to 12 weeks.

So, by synthesising the wisdom of the ages from cherished spiritual traditions with evidence based research, iWithin, the world’s first personalized transformational guide, was born.
