ELI5: How do we remember everything? Doesn't our brain get overloaded with information?

I was wondering, how does our brain manage to do it all? Doesn't our brain get overloaded with information when we think and register things to our long-time memory? How does our brain store information? It's space seems to be infinite...

The brain remembers far fewer details than you might think. It compresses and discards unnecessary information all the time. Unless you have a photographic memory (which is pretty rare), you just remember the things that stick out, and your brain reconstructs the rest based on how things like that usually looks. It uses symbols and generalizations all the time, and reconstructs memories based on how you know the world to work. 

Recalled memories are often slightly distorted each time you try to access them. It just happens little by little, so you don't notice that your memory has changed. 

We're good at remembering generic things, but bad at remembering details. Usually the brain just fills in details that are likely to exist even if we don't know for sure that they existed.
