ChatGPT in One Day
Chapter 1. Getting started·Exercise 01

Your first prompt in 30 seconds

Open ChatGPT, type one sentence, get a result. The shortest possible loop.

This exercise runs alongside the first page of Chapter 1. You will see a result in under 30 seconds.

1. Open the screen

Go to chat.openai.com. If you're logged in, the input box appears right away.

2. Type one sentence

Copy and paste this into the input box exactly as is:

Suggest a lunch for today. Korean food, something light.

Hit enter. An answer arrives in seconds. That's your first result.

3. One line to refine

In the same conversation, add:

Try again — something with broth this time.

Refining in one line is the core habit. Get one answer, then redirect with the next sentence. Once this rhythm clicks, every task speeds up.

Up next

The next exercise turns the same loop into a one-page meeting summary in three minutes.
