About Kevin Sandler

Kevin Sandler is a speaker, writer, and life satisfaction researcher known for conducting a decade-long personal experiment on happiness and fulfillment.

Since age 17, Kevin has tracked his emotional state every fifteen minutes, creating a dataset of more than two-hundred thousand personal happiness data points across nearly every major transition of early adulthood. Through high school, college, relationships, career changes, travel, van life, property ownership, and life in multiple regions of the United States, he documented how different experiences affected both day-to-day happiness and long-term life satisfaction.

Rather than offering a universal blueprint for happiness, Kevin helps people identify the specific conditions that allow them to thrive.

While most happiness advice treats those as the same thing, Kevin’s research and personal data suggest they are often very different.

Through years of experimentation, Kevin tested many of the strategies commonly recommended in self- improvement, productivity, and positive psychology.

Some worked exactly as expected. Others produced surprising results. The lessons from those experiments became the foundation of his framework for understanding life satisfaction.

Kevin’s Timeline:

From being a high school student now experience real time what it feels like to have your brain develop, and every transformative experience mapped out.

To starting college, working part-time, making friends, and beginning life on your own. Living abroad in South Africa in the process.

To then fulfilling his lifelong dream of being a barista, and transitioning back into corporate.

To then, Van Life — All 50 States, One Year Converted a van. Drove everywhere in one year. Interviewed one person in each state asking how satisfied they are with their life. Looked incredible on the outside. Taught him that freedom and fulfillment are also not the same thing.

Moving to Pittsburgh, buying a house for the first time and then transitioning to being a “homeless landlord”

Moving to California, being a young professional in his twenties, tracking the transition of what it felt like along the way.

Today – Nearly a decade of data. Radically different lifestyles. One consistent finding: there’s no single recipe for a life that feels worth living.

The goal is to figure out yours.

That’s what he helps people do.

Kevin is often described as “the guy who tracked his happiness every fifteen minutes.”

He prefers to think of himself as an obsessive experimenter who spent years turning his own life into a laboratory to better understand what makes life meaningful.

When he isn’t analyzing happiness data, writing, speaking, or working on new experiments, you’ll likely find him exploring somewhere new, documenting life through videos and stories, or asking questions most people never think to measure.
