When and How to Start?

I am so excited to become a life coach! My friend and I have signed up together and plan to run a business together to make the marketing easier. We wanted to start as soon as possible with things like website, instagram, ect to be ready to coach as soon as we’re done with life coaching school. When we enrolled we were given access to scholars and decided to slow down on the business part and focus on learning in scholars. Is that the best thing to do? And if we were to get a head start in the business where would be the best part to start????
