Yo, I’m Eric, aka Reysu!
I run a 190k subscriber youtube channel where I talk about productivity, tech, and tools to optimize your life.
I built the Life Tracker System, a paper-and-pen framework for logging habits, daily highlights, and small experiments that thousands of viewers now use.
Whether you’re a fellow entrepreneur, student, or company that wants to work together, feel free to say hi! let’s connect!
