Nobody can deny that teaching is hard. In this 15 min video, I teach how the Quicksort algorithm works the old way: with a blackboard and chalk. As you can see, I committed many mistakes. Considering that I spent 2h of preparation for this, my performance was not as good as expected.

What else could have been worse?

Wrapping up

For my new session, these are some preparation tips that may help:

  • Record me during the rehearsal: it is incredible the many mistakes that we don’t notice if we don’t see ourself during the performance
  • Move my hands and speak slowly: the corporal language is essential, this is something that I’m still learning from the best speakers
  • Practice, practice, and practice
