Early Life and Background

John Kralik, also called Mr. Thank You, leads a global movement focused on gratitude and kindness. Born in Los Angeles in 1955, he had no idea his life would one day inspire so many people. His journey toward gratitude began during one of the toughest times in his life.

Kralik grew up in a middle-class family and later became a lawyer. Over time, he earned respect as a judge in California. Despite his career success, his personal life was filled with struggles. By the time he was 52, his law firm was failing, he was going through his second divorce, and his relationships were suffering. On top of that, he faced health and financial challenges.

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 instead of the good things in his life. Wanting 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 started with family, friends, coworkers, and even service workers. Over time, this simple habit changed his perspective. Practicing gratitude helped him mend relationships, rebuild his career, and gain confidence.

By the end of the year, this daily act had completely transformed his life. He began appreciating small moments and experienced personal growth.
