I am getting peeved seeing everyone characterize mining (and only mining, it seems), as a "grind." It is no more a grind than running mission after mission of goods delivery, data courier duty, planetary scan missions (boy, did I do a lot of those!), CZ combat, REZ visits, or sussing out Guardian secrets for a mad scientist. Traveling from system to system, honking and scanning and mapping, can be tedious as hell, but that is an explorer's meat and potatoes, right? Everything takes time and effort, but that does not make everything a "grind," or if it does, then the word becomes meaningless.
Maybe you don't like mining because you're not very good at it -- combat missions can have the same drawback. Maybe assassination chores violate your Commander's personal ethics -- who knows? Trade Elite was my last of the three to earn because I am not that fond of hauling cans of sh*t for pay (or most other commodities as well) but I did it because it needed to be done to get me where I am now in the game. That is not a grind, it is how the game is played. "Grind" seems to me to mean "I don't want to make the effort, so it should be made easy and fast just for me."
