The benefits of keeping a journal(日志)

    If you want to grow, one important thing you should do is keep a journal. It may seem simple, but it can make a big difference in your life. I have been keeping journals for years. Writing all the lessons I learn and all the ideas I get has become a habit for me. {#blank#}1{#/blank#} Here are some benefits you will get by keeping a journal.

♦ It prevents you from losing an idea. Have you ever gotten an idea and lost it later because you didn't write it down? {#blank#}2{#/blank#} But then I developed the habit of writing down every idea that came into my mind as soon as possible. If I am away from my computer, I usually write it down on a piece of paper that I bring wherever I go. I will then transfer the idea to the journal in my computer.

♦ It helps you review all the lessons you've learned. By reviewing your journal, you can quickly see the lessons you've learned and the ideas you've gotten. {#blank#}3{#/blank#} You can use the ideas to propel yourself forward.

♦ {#blank#}4{#/blank#} After keeping a journal for years, you can look back at it and see how far you've gone. Things that were big problems in the past might seem small today. The raw ideas you had in the past have been realized today.

♦ It helps you expand your ideas. When you try to come up with a sentence to express an idea, you are thinking actively about it. {#blank#}5{#/blank#} In the end, you will expand your ideas.

A.I often experienced that myself.

B.It trains you to express your thoughts.

C.It allows you to see your progress over time.
