Don’t feel like you have to find a specific topic to post about. Many people fall into that habit/trap.

The most important thing is to find an audience. Which can often involve posting on various topics and using a variety of tags.

Networking is also a vital activity. Find some good channels on Discord and Steemit chat. You’ll soon make some invaluable friends and will have yourself a frequent audience of people who take the time to read your content.

Edit: Lol... I just realised you posted this 6 months ago... I guess you never gave content creation a real go.
