When faced with a critical situation like the Cuban Missile Crisis, President John F. Kennedy maintained his official schedule to stay productive and avoid falling behind on other pressing issues. This approach is echoed in six other US presidents who shared productivity tips, including prioritizing tasks consistently, letting go of non-essential tasks, automating life, exercising regularly, investing time in one's partner, setting rules for how to treat others, and focusing on what truly matters. By adopting these principles, individuals can improve their work-life balance, increase productivity, and lead a more balanced life.
