Oh man, I'm learning the basics of Hiragana right now and, while it is fairly simple it's very tiring.
I tend to give up on things easily for a while until I get the energy back but hopefully, I'll be able to pick up Japanese because I like the language and it sure is giving my brain a much-needed exercise.
Gotta say though it is a pretty rewarding feeling when I do recognize a Kana even though I don't actually know what the word means.
