Is it laziness?

Lately, I have been having trouble, well, I think always have and I am just accepting defeat now. I am either a lazy reader or have a hard time concentrating. Every time I go through my RSS feed and find something I want to read, I often skip every other sentence or paragraph (depending on how long the post is), like I don't have the patience to calm down and read. Maybe this is why audio formats are more appealing to me or more likely to stick to them.

So I ask myself, is this laziness and lack of discipline, is it ADHD, or it's just the way it is?
