Posting on Social Media

Hi there. I am a life coach who has yet to get my second client. I have heard that I should be posting on social media daily but I dont know what to post. It is important to me that my offerings are value-added, not just indulgent selfies, but I don’t know what to offer daily that is meaningful. Do you recommend posting daily and if so, where/how should i get my content? Any help is appreciated.
