How to actually prompt ChatGPT

The single biggest mistake new users make: treating ChatGPT like Google Search instead of like a colleague. Search-style prompts ("best AI tool") get vague answers. Colleague-style prompts get useful ones.

Bad: "best AI tool" Good: "I'm a freelance copywriter who writes 3 client articles per week, each around 1,500 words. I want to spend less than $30/month and need the tool to support my voice across clients. What should I pick and why?"

Five prompt patterns that work

1. Role + task + constraints

"Act as a [role]. Help me [task]. Constraints: [list]. Output format: [format]."

2. Brainstorm then refine

"Give me 15 ideas for [topic]. Then pick your top 3 and explain why."

3. Explain like

"Explain [concept] like I'm a [audience]. Then give me 3 analogies."

4. Critique

"Here's my draft: [paste]. Critique it as if you were [editor type]. Be specific and harsh."

5. Iterate

"Rewrite that in half the words." → "Now make it more conversational." → "Now add one specific example."

Features most people miss

Custom Instructions (Settings → Personalization), tell ChatGPT once about your job, tone preferences, and how you want responses formatted. It applies to every conversation.
Projects: group related chats together with shared context files
Voice mode: talk to it during walks; the conversational interface is genuinely different from typing
Custom GPTs: pre-configured assistants for specific tasks (writing, coding, research)
Memory: let it remember key facts about you across chats
