This doesn't mean learning things is easy. I once had this chemistry student i remember. She was pre-dental and drew as a hobby. I would tell you her art was gorgeous. She was obviously very smart but she had some sort of block around O-chem. She kept a good attitude and kept trying and her final exam score went up a ton, and she passed the class. I assume now she is doing dental work somewhere and being excellent at it.
As for disabilities, I once was a guild lead in another game where the gameplay was much faster paced and the fights were far less forgiving than they are in FFXIV. Sadly this meant that if people couldn't keep up with mechanics or damage, I had to bench them or else i was making the other 19 people waste their time. I had a player who was missing two fingers on his hands due to a machining accident, which I felt HORRIBLE about, but i was forced to bench him. Unbeknownst to me, he made an alt, kept trying, kept practicing, got quite good, and earned his spot back. I was super happy and proud of him.
Even now I am changing careers and going through a difficult job search. I DREAD checking email and LinkedIN every day. I feel anxious, depressed and angry every time I think about it, which is anytime i have about 10 spare seconds. I still force myself to do it because there is no other way I will ever reach my goals no matter how hard it try.
The best teacher in life is failure. Us humans, we are imperfect beings with strong emotions, flawed heuristic decision making, and often times do incredibly stupid things against our own self-interest. This is NORMAL. Feeling that fear, that anxiety, the crushing defeat of failure, getting frustrated or angry, contemplating quitting and giving up - this is the gameplay loop of human life. If we want to achieve our goals we have to keep on trying. The people who are successful in this world, they decided to try, i'm sure they failed, but they didn't give up and go home. If you love this game, or if you love anything, you gotta keep doing it and getting better.
