If you want your followers to keep up with you, posting once week will not do the trick.
If you are a perfectionist and revise your blogs 10 times before posting, you can try a 3 step plan:
1. Update your followers daily about what you are working on
2. Share finished parts of your post daily instead of a long post every week.
3. Post now revise later. Post something and then you can make editing, revisions etc.
Bonus: You can also make a category like this for your updates
Here is an update example about one of my goals of 1 year. Do not wait 1 year to share your progress, share them as they become “some progress”.
