I'll just say, it appears that everyone is just more adept or not at some things than others are, or as said, can be experiencing something that impedes your ability at the time. That is why I do not like if it is implied or expected that we are all equally capable and are all the same mentally and physically. Just as how some were better at Art and English, than Math or could adapt to certain tasks better than others, being more organizational, etc.

I think some things are not designed very well and may make them confusing. I will see how some websites for instance are very well designed and easier to navigate within than others. One will have an idea, then others are supposed to see it as they do. I don't know if this will apply here, but just a thought.
