Balance is another word for trust
At any moment, there are many things to balance that are important to you. At any moment, one will be more essential to tend to than another.
Living a balanced life does not mean you figure out how to balance your time and energy equally amongst things ahead of time. Instead, it means you pay close and curious attention to the present moment and sense what is most vital now.
Balance is the practice of meeting life precisely as it is and exactly as you are, not being rigid about the way things should be or you should be.
