I also used this post to experiment at my level: @thatcryptodave/what-s-a-rising-star-without-ego

Anyway, I tend to agree with that, maintaining an ego at 0% at all costs or finding the right ego ratio for each mission played, it's up to everyone to see how to organize their game but it should not be made a primary objective at the outset. Playing habits are very quickly acquired while at each step, you have to review your strategy, this is the real ego to manage :).
