For things to change, you’ve got to change. For things to get better, you’ve got to get better. It’s easy to do. But it’s easy not to do, too.

The Slight Edge

I am on a mission to demonstrate how we, human beings, are capable of much more than we might have initially thought, to show how to make life richer and happier, and to provide guidance for finding and reaching goals we are looking for.

I am positive that the profound change is not only possible, but also very easy. Whoever you are, wherever you come from, whatever you went through, the only thing you need to have your dreams come true is already in your possession. My role is to show you how to use it properly.

My name is Jan Zavrel and I am Biohacker, iOS & Web Developer, Author, Teacher, Lifelong Learner, Evernote Certified Consultant.

My ultimate goal is to live long enough to live forever. I got inspired by Ray Kurzweil's book Transcend: Nine Steps to Living Well Forever. To be alive has a special meaning and value for me. I consider it a privilege to be able to wake up in the morning, inhale a fresh air and greet a brand new day. Unfortunately not everyone has been that lucky. Among them my mother, who died when she was 47, my brother when he was 30, and my wife when she was 26 years young.

My consulting services are focused on nothing less than redesigning your lifestyle so you can live a longer, healthier and happier life. Ultimately, to live forever. I know it sounds like a crazy joke or sci-fi, but it's immensely motivating.

On my journey, I embrace the philosophy of Jeff Olson's Slight Edge. It is constantly reminding me, that I can achieve anything I want. All it takes is to give it just a few minutes each day and stay persistent.
