With sparkling eyes and a gaping mouth, I watched a TED-Ed talk on YouTube with pure admiration for the dauntless speaker. Thinking about my palpitating heart and sweaty palms during my class presentation, I wondered how anyone could simply be so confident in front of that many people. How were they able to overcome the piercing stares of the congregation? How were they able to speak with such conviction that you know it fully stems from passion? How were they able to convey their fervour for the subject matter not just through their words, but through their body language and voice modulation?
