Pick an interest you enjoy. The best Instagram accounts have a focus, and yours should, too. However, you shouldn't just pick something out of the blue. Base your account around something you enjoy. If you're passionate about it, your followers will know!
- Really, it's up to you what you focus on. You can do food, makeup, travel, embroidery, poetry, or even slime. As long as it has a visual component and it's something you enjoy, go for it!
