Flexible hours: YES

Based on my research, the AI e-book and digital publishing services side hustle typically offers a high level of flexibility when it comes to setting your own schedule. Most individuals can work on their projects at times that suit them best, allowing for a good work-life balance. Online discussions suggest that this flexibility is genuine and not just a marketing ploy. However, some users have mentioned that there may be occasional time commitments related to client deadlines or project milestones. Still, overall, the consensus seems to be that the hours are quite flexible, with the ability to adjust workloads based on personal preferences.
