Learning Better When You're Active

When I'm sitting in a classroom or even just sitting in my apartment, learning independently, I can't concentrate as well. My concentration goes down. The best is to walk outdoors; you can do it inside too. So when I'm listening to Japanese many times, I will just walk in a circle in my kitchen. And even this is much better than just sitting. It keeps my body more energized,. therefore my brain, right, more energized, my concentration is better. Everything works better.
