Health Coaching Business and NOT using Facebook

I am starting my own health coaching business. Most people that I see that are successful coaches use Facebook as their platform for getting seen and getting clients. So many business coaches out there tell you that you need to use Facebook, but I just don’t want to. I feel like it’s overwhelming and a lot of “noise” in my brain and a distraction. Do you think I can have a successful health coaching business without using Facebook. I currently use Instagram to post encouraging words and to let people know I’m a coach. I guess the big question is, if I don’t use Facebook, how will I get clients. Would love your opinion on this since you are a successful coach.
