ELI5: Explain Like I'm 5

Concentration

When you're doing something, like playing with toys or reading a book, you need to give it your full attention. Concentration is when you focus hard on something without getting distracted. It's like when you're building a big tower with blocks and you have to make sure the blocks don't fall over. You have to really concentrate on what you're doing so that your tower doesn't fall down.

Sometimes it can be hard to concentrate, especially if there are lots of other things around that are more interesting or exciting. But if you practice concentrating, it will get easier and you'll be able to do more things without getting distracted. So just like you have to practice building your tower with blocks, you have to practice your concentration too!
