(a.k.a. how the stars aligned to make me so passionate about caffeine, energy drinks, and fatigue)
My primary goal, right from the beginning, was to help people understand caffeinated drinks like I do, as if they were seeing these drinks through my green eyes. That’s how this moniker was born.
When Monster Energy hit US markets, I had just started my advanced studies in nutrition and biochemistry. I heard the hype, I read the news stories about kids having energy drinks for breakfast, and I knew how and why energy drinks worked thanks to my college courses. I was immediately fascinated by these caffeinated products, and that’s when the dream to write a book and my insight with others began.
I earned my bachelor’s degree in biochemistry from the University of California San Diego and a master’s degree in food science and food biochemistry from the University of California Davis. I grew up without energy drinks and without coffee shops on every corner.
I hated the bitter taste of coffee and tea and learned to live without soda thanks to those years of wearing braces. In short, I learned how to make do without caffeine. And yet, I could not have survived college and grad school without caffeine. I had to balance two part-time jobs as a full-time student. I couldn’t have done this without caffeine in general and energy drinks in particular.
During grad school, I developed a system called the “5 Levels of Fatigue”. It started out as a system to help people consume caffeine more systematically – if you always drink the most potent drinks, caffeine’s not going to work on those days you need it the most.
As I grew as a professional, so did my beloved “5 Levels of Fatigue” system. This system has evolved so it is not just for caffeine consumers. The 5 Levels of Fatigue helps companies of all sizes and industries improve employee engagement, satisfaction, and retention. After all, fatigue isn’t just about caffeine and a good night’s sleep – it’s also about boredom and mental stimulation.
