If you write a diary every day, this diary will be your stepping stone.what happened to me today? What did you experience, good or bad, and what did you think about it? Where do I record my inadvertent thoughts and memories? Will there be any problems with my mentality even if I face tomorrow without organizing my day? If not, how can you organize your thoughts? "Diary" has become a necessity for busy and weary modern people who have a job or social life. If you write in a diary and organize your mind, dissonance with your boss, unresolved work and interpersonal relationships, etc. will at least ease the burden on your mind and help you solve problems.
