During a chess tournament in Greece in 2008, I and a German GM had a fun conversation with two young jolly blokes from Turkey who were sure it was no comfortable career being Chess players in their country.
"But then, how do you hope to lead a good life?"
"You know, we can become Chess coaches. There's good money in coaching".
"But aren't you playing serious tournaments here?"
"You know, we want to become Grandmasters, and then become costly coaches!!"
(A Grandmaster coach and a regular coach)
I was chuckling for days on that, but the German wasn't impressed. He was distraught with the notion that anyone can choose to be a teacher, without having any passion and qualities for the role.
