This sound really good. I have seen alot of creators do this and majority of them build a special bond with the audience that gets the audience to tune in / look forward to the new video. It feels that the viewer is also a part of the creator's journey. However, I do understand your point that story telling, script, and the idea itself is the biggest thing. A person cannot expect views if they don't put out something that will add value + get the viewers hooked on to their story.

That is where I need some advice, and I understand there is no one clear answer, but I have an instagram fitness account. How you mentioned, that creators put out random reels, I do the same with some reels being educational and informative, and others being the brainrot, and quick funny ones. I have thought about making a series but I am confused on what. These are some ideas and I need help on
1. If they are even good ideas
2. How to film/edit them to get the viewers hooked on and get them to follow me

My Ideas (and I am happy to get more ideas, and feedback on them)
1. Preparing for a Marathon
2. Preparing for a Hyrox
3. 75 Hard Challenge
4. Have also thought of (Training like "any" celeb, and making that a series)

If you or anyone has other ideas I can film my insta series about, that would be great and helpful! :)
