Or...

It can spend hours and hours doing what it finds interesting.

It can maintain that interest for years.

It doesn't have a problem with concentration.

When it has to do something that doesn't provide a direct and immediate benefit to itself....it can't.

It seems to have difficulties concentrating on tasks it doesn't like doing.

It tells us it has ADHD.

How convenient and tragic victim friendly is that?

It's a self absorbed narcissist.

Kinda makes sense doesn't it?
