“Good morning. Today I'll be looking at the secret life of ocean currents. There are three things I want you to take away from this lecture. Firstly, currents are rivers inside the sea. Secondly, they carry heat around the planet like a conveyor belt. And thirdly — this is the part that matters for California — they decide our weather before our weather decides anything.”
“Let me give you an example. In other words, think of the Pacific as a giant bathtub with the taps running. Turning now to the deep ocean — and this is where it gets strange — some water down there hasn't seen the sun for a thousand years. So, what does all this mean for us? To sum up: the ocean is not scenery. It is the engine room. Next week, we'll examine what happens when the engine slows down. That's food for thought until then.”

🎤 Your turn to speak
Give a one-minute mini-lecture on any topic using six signposts: framing, firstly/secondly, for instance, in other words, turning now to, and to sum up.
Say it out loud three times. Even better: record it on your phone and listen — your ear is your best teacher.

Good morning, everyone. Today I'll be looking at the strange power of habits — why small actions beat big promises. There are two points I want you to take away. Firstly, habits run on autopilot: in other words, they cost almost no willpower. Secondly — and let me give you an example here — a reader of two pages a night finishes twelve books a year. To sum up the opening: you don't rise to your goals; you fall to your systems.
