ChatGPT at Work: 3 Mistakes That Cost You Dearly
Most professionals use ChatGPT at 10% of its potential. Here are the 3 most common mistakes and how to fix them.
The Problem Isn't the Tool
You use ChatGPT every day but your results are mediocre? Generic answers, tone that feels off, content you can't use as-is. The problem isn't the tool. It's the way you talk to it.
The difference between a user who saves 30 minutes a day and one who saves 3 hours comes down to three mistakes to fix.
Did you know?
90% of users never ask for revisions on AI-generated content. Iterating on prompts with context, role, and constraints can turn 30 minutes of daily savings into 3 hours.
3 Mistakes Everyone Makes
1. Prompts that are too vague.
You write: "Write me an email for a client." The AI gives you a generic, flat text.
Write instead: "Draft a follow-up email for a Belgian SME prospect in the construction industry. Professional but warm tone. Goal: get a meeting. Maximum 100 words."
The result is immediately usable. The precision of the prompt determines the quality of the response.
2. No context.
ChatGPT knows nothing about your company, your industry, or your audience. If you don't provide that information, it makes things up. Always include: the role the AI should play, the context of your request, the target audience, and the desired format.
Before: "Summarise this document." After: "You are a CFO. Summarise this quarterly report in 5 bullet points for the board of directors. Focus on budget variances and risks."
3. Accepting the first result.
90% of users never ask for revisions. That's like accepting a first draft from an intern without proofreading. Iterate. Say "More concise", "Add figures", "Change the tone". Each iteration improves the result dramatically.
