How do early-career researchers handle the challenges of getting their first paper accepted?

Publishing my first study has been tougher than I expected—between formatting requirements, strict reviewer comments, and multiple revisions, it feels like an uphill climb. I’ve been reading about scientific article publishing services that claim to guide authors through submission and editing, but I’m unsure how reliable or necessary they are. Do these services genuinely help researchers understand the process, or do they just make it easier to get published without learning the ropes? How do others manage this stage without losing motivation?
