Jesse Itzler emphasizes the importance of closing out the year by decluttering both physically and mentally. He suggests starting with a personal audit to review the past year, identifying what worked and what didn't. This includes cleaning out closets, desks, and digital spaces to enter the new year feeling 'light.' Itzler also highlights the significance of writing handwritten thank-you notes to those who impacted your year positively, which he believes fosters genuine connections and gratitude. For the upcoming year, Itzler introduces the concept of 'Misogi,' a Japanese ritual where one undertakes a significant, year-defining challenge. This could be a personal or professional goal that pushes boundaries and creates memorable experiences. Additionally, he advocates for 'Kevin's Rule,' which involves planning mini-adventures every couple of months to break routine and maintain excitement. Itzler stresses the importance of adding one winning habit each quarter, which cumulatively leads to significant personal growth over time. He underscores the necessity of planning these activities and habits in advance, using a physical calendar to visualize and prioritize them.
