You’ll decide which ideas to keep and which ideas to cut. In this lesson you'll learn how to articulate your big idea in the form of something called a "throughline," which will be the main idea of your talk and your roadmap for your talk. To prepare for this lesson, review the questions below and begin narrowing down the short list of ideas that you came up with in the last lesson to the 1-2 ideas you could imagine fleshing out into a full blown talk. Remember, you can use the TED Masterclass process to develop more than one talk. You just need to develop one at a time. So, feel free to choose one idea and save the others for future talks.
