I handle the Mals for the local rescue and have a rescued one myself. You tell people about drive and energy, they nod their heads. The reality though is outside the capacity of peoples comprehension. Even if you see it first hand the reality is that it goes all day and all night. Like the terminator, it never stops... AKC breed description says "make bad pets". I'm not exactly sure how I manage but, I have... A fairly serious case of ADHD maybe makes me similarly hyper focused and a good match, I'm not sure. Mine does insane frisbee tricks. We work on it constantly.
They're tools not toys.
