You’re starting a project or a new exercise plan, and it’s in shaky, new territory for you. You feel doubt about whether you can do it, and so you’re tensely doing everything you can to make sure it will turn out the way you hope.
The stress, fear, doubt, and tension you feel likely come from an attachment to how things will turn out. For example, we want to lose weight and get fit through exercise, or be brilliant at our new project and have everyone think we’re wonderful.
