(Note: I use AI to help me translate my stories from Japanese to English.)
I have been writing a diary for 10 years. There are some days when I don’t write, but most of the time I write every day.
I write about what I did, what I thought, what happened, my weight, and my ideas.
Since you are the only reader of your diary, you can write honestly. It helps relieve stress.
I can continue writing a diary because it relieves my stress and makes me feel good. I also want to keep a record of my life.
There are several benefits to writing a diary.
- You can notice your growth
- You can relieve stress
- You can notice your condition
- You can record your memories
- You can restore your confidence
- You can notice small changes
1. You can notice your growth.
I study English and record my study history. When I reread my diary, I can see my improvement in English.
2. You can relieve stress.
You feel stressed when you keep your feelings and opinions inside. However, if you write a diary, you can express them. Then you feel better and less stressed.
3. You can notice changes in your condition.
For example, I sometimes have diarrhea. I wrote down when it happened, and I found that it only occurred when I went to work.
4. You can record your life.
Without writing a diary, you will forget most of your experiences. However, if you keep one, you can remember them clearly when you read it.
People who keep journals have life twice. —Jessamyn West
If you write a diary, you can enjoy life more.
5. You can restore your confidence.
People often forget what they have accomplished, and as a result, they lose confidence. However, if they write a diary and read it from time to time, they can remember their achievements and regain their confidence.
I sometimes lose confidence and feel that I haven’t accomplished anything. However, when I read my diary, I remember my experiences and become confident again.
When I receive a compliment, I write it down in my diary. These words boost my confidence.
6. You can become more attentive.
If you write a diary, you try to find topics to write about. As a result, you become more attentive and notice small changes, such as changes in the seasons and in yourself.
Do you know a person called David Goggins? He is regarded as the toughest person in the world.
He is the only person who has completed SEAL training, Army Ranger School, and Air Force Tactical Air Controller training. He has also completed more than 70 ultra-distance races. He set a Guinness World Record by completing 4,030 pull-ups in 17 hours.
He writes a diary about his weight, sleeping hours, and training.
He said that because he writes a diary, he can find his weaknesses and improve them.
I collected some quotes about diaries.

Writing a diary is like whispering to yourself and listening to yourself at the same time.

A personal diary is an ideal environment in which to express yourself freely. It is a place to think, feel, discover, grow, remember and dream.

Writing in a journal every day allows you to focus on your skills, the things you are grateful for and the things you want to do better in the future. It helps you to enjoy every day of your trip more.

The only thing I’ve been really meticulous about in my life is keeping a diary. I have hundreds of them, full of feathers, flowers, photographs and words – unlocked, lying open on my shelves.
–Terry Tempest Williams
You can understand your true feelings by writing a diary. You can also discover your preferences and goals in life.
You may think that you already know yourself well. However, writing a diary helps you understand yourself more deeply.
Your diary might be the most interesting book. You are the author of your life and your diary. It depends on you whether your diary becomes interesting or not.
