Choice of language for my business


I am starting my coaching business, 6 months in, I can coach in the 3 languages, I speak french ( my first language), english and spanish fluently and I don’t know if it is better to write in the 3 languages on social medias ( its time consuming and I don’t know how to do for the videos) or if I should choose one language and focus on this language to coach too.

I would love to know what do you think?
Thank you
