Master N3 Grammar: Expressing Habits with ことにしている vs ようにしている

In Japanese, talking about your habits goes far beyond simply using the present tense. To sound natural and precise, you must express how you approach these habits.

Today, we will master two essential JLPT N3 grammar points: 〜ことにしている and 〜ようにしている. While both translate roughly to "I make a habit of..." in English, they carry distinct nuances of strict commitment versus conscious effort.
