Both yes and no.

No, because you, as a human, have to think about the future, too. Otherwise you would make poor choices for your health, about your finances and stuff.

And yes, because they enjoy the simple things. Going for a walk. Watching a small child, a cat, a ball. Meeting people.

I love those walks with Nefnef, because they make me stop and relax. No thinking of the future or the past, just chatting with her and experiencing the world through her eyes.
