Treat the long video as raw material, not as something to summarize. Mark self-contained moments with a strong hook and payoff, cut each into a vertical-native clip, then rewrite the opening, captions, and packaging for each platform.
You may be burning out from the constant comparison and daily decision load, not from a lack of discipline. Stop using other creators' visible output as your required cadence, reduce the number of weekly content decisions, and choose a publishing level your business and health can sustain.
Stop trying to invent content from a blank page. Build an idea capture system around customer questions, comments, sales calls, recurring problems, old winners, and your own work, then rotate each raw idea through different formats and angles.
If content creation is harming your mental health, consistency is no longer the first goal. Reduce the load, protect recovery, identify which content actually drives the business, and rebuild the system so publishing does not depend on daily personal output.
Delegating editing works when you transfer taste, not just footage. Give the editor a small style guide, reference videos, annotated examples, non-negotiables, audience context, and feedback that explains why a change matters.
