This is the first pillar because it is by far the most important. Your mind is one of the only things you can truly control in life. While you may not be able to control external circumstances or other people's actions, you can control your own thoughts, emotions, and beliefs. When you focus on improving your mindset you will be better equipped to navigate challenges and setbacks along the journey. Once you master it, you'll be able to use it to manifest anything you want in life.
