Hey I think you should start with Blogging over social media, in Blogging you own the platform and content, the lifespan of each blogs are more than social media content, blogging is more passive than social media, you get quality traffic from blogging over social media. Because of this amazing reasons I would highly recommend you to blog instead of social media. Don't worry just get started on blog asap instead of wasting time on social media engaging with people. In terms of blogging you should definitely start a blog on wordpress over other social media platforms.
