＜Chat GPTによる具体的な修正箇所と理由＞
Original: From Today, I'll try to keep a diary in English every day.
Correction: From today, I'll try to keep a diary in English every day.
Reason: "Today" should be lowercase because it is not at the beginning of the sentence and does not need capitalization.

Original: Because, I have to improve my English due to my current job.
Correction: because I have to improve my English for my current job.
Reason: The word "because" should not be capitalized or preceded by a comma when it follows a sentence. Additionally, "for my current job" is more concise and natural than "due to my current job."

Original: It's too much trouble to memorize words and even more trouble to memorize grammar.
Correction: No change needed.
Reason: This sentence is clear and correct.

Original: From junior high school to today, I have never been able to continue studying English.
Correction: From junior high school until now, I have never been able to continue studying English consistently.
Reason: "Until now" is slightly clearer than "to today," and adding "consistently" emphasizes the ongoing nature of the difficulty.

Original: That is why I decided to try my own method.
Correction: No change needed.
Reason: This sentence is clear and correct.

Original: The only thing that I can do everyday without any difficulty is to write, if possible.
Correction: The only thing I can do every day without any difficulty is write, if possible.
Reason: "Every day" should be two words when referring to each day, and the infinitive "to write" is not necessary after "is."

Original: So I decided to write a daily diary in English.
Correction: No change needed.
Reason: This sentence is clear and correct.

Original: Of course, using DeepL.
Correction: Of course, I will be using DeepL for assistance.
Reason: "Using DeepL" is a fragment; the full sentence "I will be using DeepL for assistance" is clearer.

Original: Humble daily, grateful daily, small efforts everyday will eventually produce big results.
Correction: Humble daily efforts, grateful reflections, and small actions every day will eventually produce big results.
Reason: "Humble daily, grateful daily" needs more context to be clear. "Efforts" and "reflections" provide better clarity, and "every day" should be two words.

Original: That is what I believe.
Correction: No change needed.
Reason: This sentence is clear and correct.
