日本語を上手になりたいので、これを使ってみようと思います。
今日もまた、日本語の勉強にてきとうで自分に失望した。

I want to improve my Japanese, so I will try to use this.
Today again I am disappointed in myself for being lazy with my Japanese language studies.

EDIT: I cannot edit my original text, but I think that's the point so that the corrections below would make sense. Thanks for the corrections!
