Review yourself. When was the last time that you experience the complete transformation of yourself including body, mind and soul? When you commit yourself to achieve a specific goal, you work hard and experience a complete transformation according to the desired goal of your life.
Similarly, when you think of Yoga teacher training, it encourages you to look at the pattern that is not the realm of your ultimate life. Yoga teacher training, it focuses on goal setting but it is not all about chasing a goal rather it is like transformation of yourself - your lifestyle, your vision and your inner being.
