For many people, that first step of being true to themselves will be the most difficult. Authenticity for me is the easiest part. I think being inauthentic to who you are is the biggest sin.
Having a more niche area or expertise to start with is the next most important piece. I can be myself 24/7 a day and put out content but if I don’t have a focus of some kind, it would be nearly impossible to build a base.
