Focus on one area

Hi Brooke and all the incredible coaches
so i was just listening to Brooke’s first coaching call for the month and she mentioned to one of the ladies she coached that she should be using all the tools she is learning and using them on one area of her life (business, weight, relations … etc)
so i just want to be clear on how i can apply that;
i would LOVE to launch my health coaching business, so does that mean that i should be doing ALL the models and feelings exercises on this topic ONLY???
