Does your adhd person dismiss... just about everything?

"It'll be fine."

I hear this about so many life issues.  From tax questions to health concerns to car maintenance to issues with kids to... yeah.

His way is to say that it will be fine and do nothing.  And then when later it isn't fine, he's angry that he has to take time to fix it or spend the chunk of money to fix it.

 I'm trying to decide if this is because fixing problems when they are small is boring, or if he's just in denial about everything.  Is it all really just about having his pleasures at all times?  Or is it more of his lack of taking responsibility for things, which I see a lot of, too.  I suppose I may never know.
