I like to remind teachers that even though they're all overwhelmed and overloaded, and it's easy to get burned out, it really is about the kids. It only takes one good teacher to change a life - one time, and one book. That's what happened when I was a kid. I had one good teacher that came in at the right time and turned me into a writer. So never lose sight - you could be that teacher.
I decided to do philosophy at university, with a view to becoming a professional philosopher. Being a rather unstable character, at some points I had doubts about becoming a professional philosopher, but the example of two of my teachers, Ezequiel de Olaso and Juan Rodriguez Larreta, made me confirm my original decision.
