There is no one definitive answer to this question, as it depends on a variety of factors. Some bloggers may decide to stop blogging after a certain period of time has passed, while others may continue blogging until they retire.
Ultimately, it is up to the individual blogger to decide when they believe it is time to call it quits.
Some factors that may influence when a blogger decides to stop blogging include the size and scope of their blog, their audience size, and how well they are enjoying writing. Additionally, some bloggers may only blog sporadically or for short periods of time before stopping altogether.
It is important for bloggers to be mindful of their own motivations for blogging in order to make the decision to stop when it is right for them.
