More prompts do not equal more output. The real measure is time to a finished, usable result, including your own checking and fixing. Pick three recurring tasks, such as a weekly report, a client email and a research summary. Time them for a week without AI, then for a week with AI, counting the full effort including corrections. Note how many fixes each draft needed and whether quality improved.
Typically AI helps most with first drafts, summaries and structuring, and least with tasks that need precise facts. If you keep correcting the same mistakes, improve the prompt with context, examples and a format, or stop using AI for that task. Review the log monthly and keep only the uses that pay off.
