I was explaining Defense Grid to my friend the other day and I went to say that it got difficult quickly, but I retracted that statement and said that it got challenging quickly. That started me thinking about the difference(s) between the terms "difficult" and "challenging". Are they two words for the same thing? Does one lead to the other? Do they have different connotations?
I haven't quite come to a solid conclusion for myself yet, so I wanna hear what you guys think.
I don't think they're synonyms, just two words with relatively similar meaning. "Challenging" implies "difficult", but it also implies that in/upon doing/accomplishing whatever it is that is challenging there is either a certain amount of enjoyment, or a certain feeling of accomplishment, or some form of a satisfying reward.
For example if, for whatever reason (medical or otherwise), you had to choose between having your leg amputated or having your arm amputated, you would probably say that that choice is difficult, but you wouldn't say that it is challenging.
