Your social media account is your face. It's essential to occupy a specific niche of interests and maintain your profile following them. If you know a lot of healthy food recipes, and the gym is your second home, then you can easily make a blog about a healthy lifestyle. Or, for example, you work as a photographer and want to share breathtaking pictures with a large audience.
Use your hobby as a tool to promote your page, find the feature that will make you stand out from the general mass of influencers. In such way, you`ll gather your active audience.
