Why do we get used to everyday things? Well as human beings, we have limited brain power. And so our brains encode the everyday things we do into habits, so we can free up space to learn new things. It's a process called habituation and it's one of the most basic ways, as humans, we learn. Now, habituation isn't always bad. Remember learning to drive? I sure do. Your hands clenched at 10 and 2 on the wheel, looking at every single object out there — the cars, the lights, the pedestrians. It's a nerve-wracking experience. So much so, that I couldn't even talk to anyone else in the car and I couldn't even listen to music. But then something interesting happened. As the weeks went by, driving became easier and easier. You habituated it. It started to become fun and second nature. And then, you could talk to your friends again and listen to music. So there's a good reason why our brains habituate things. If we didn't, we'd notice every little detail, all the time. It would be exhausting, and we'd have no time to learn about new things. But sometimes, habituation isn't good. If it stops us from noticing the problems that are around us, well, that's bad. And if it stops us from noticing and fixing those problems, well, then that's really bad.
