It reminds me a friend of mine who wanted to quit his career as chef in order to become a professional player of Magic:The gathering. He even lost his partner over that choice he took.
He lesson children and young adults are supposed to take from those experiences others have gone though is: no everyone will reach the status of being a professional e-professional, and even if they did, that is a life style which is not suitable for everyone who wants it.
Wasting his profession as a professional chef just to become an E-Sport player, he couldn't stop thinking about how he could think of making E-Spot his main income, wouldn't even guarantee anything.
E-Sports may be the best profession for gamers, but they have their own time, it won't last long and some events won't always exist.
It's better to do work that has real results and that's the main job, E-Spot may only be part of a hobby that can make money, nothing more.
