Early Life and Background
John Kralik, also known as Mr. Thank You, leads a worldwide movement centered on gratitude and kindness. Born in Los Angeles in 1955, his early life gave little indication of the impact he would later have. His journey toward gratitude started during a tough time in his life.
Kralik grew up in a middle-class family and pursued a career in law, eventually becoming a respected judge in California. Despite his professional achievements, his personal life was filled with struggles. By 52, he was facing serious difficulties—his law firm was failing, he was going through his second divorce, and his relationships were falling apart. Health and financial troubles made things even worse.
A Life-Changing Decision: A Year of Gratitude
In January 2008, while hiking in Pasadena, California, Kralik had a powerful realization—he had been focusing too much on his problems and not enough on the good things in his life. Determined to change his mindset, he set a goal: to write 365 thank-you notes—one every day for a year—to people who had made a difference in his life.
He began by thanking family, friends, coworkers, and even service workers. Over time, this simple habit changed his outlook. Practicing gratitude helped him repair relationships, rebuild his career, and boost his confidence.
By the end of the year, this small daily act had transformed his life. He started appreciating the little things and experienced deep personal growth.
