What causes lack of attention?

A lack of attention happens when your brain gets distracted by something more interesting than what it's supposed to be doing.

Imagine you're playing with your favorite toy, let’s say it’s a bright red ball. But then, a shiny green car rolls by, and suddenly, all you want to do is chase that car instead of playing with your ball. That’s like lack of attention, your brain went from focusing on one thing to getting distracted by something else.

Sometimes, the new thing that catches your eye is just too fun or too loud. Like if you're listening to a story, and then someone shouts "Hey!", that shout might feel louder than the story, so your brain switches focus.

Other times, you’re just tired or bored, and your brain needs a break. It’s like when you’ve been running around all day, suddenly, sitting still feels harder than it should be.

So, lack of attention isn’t because something is magic, it's because your brain is choosing to focus on the thing that seems most interesting or easiest right now.
