Nobody is born good at public speaking. The smooth ones just sweated through more rough talks than you’ve seen.

What looks like natural ease is almost always accumulated exposure. You are seeing someone’s hundredth attempt and comparing it with your third, which produces a conclusion about talent that the evidence does not support. The nerves do not vanish either, they just stop being the main event.

Get the early rough ones over with somewhere the stakes are low. A small group, a recording, a room of people who are also learning. Count talks given rather than talks gone well, at least for the first while.
