I love this Newsroom article from LDS.org on the importance of keeping a journal.
I am grateful that my mom got me a journal for my eighth birthday. I am grateful that I have felt to keep a journal since then, even if plenty of the the things I wrote as I grew up are surely embarrassing. Writing has helped me grow closer to my Savior and to record the things He has taught me. Reading my own thoughts has helped me to see in retrospect how the Lord's hand has guided my life. And now that I am old enough to want to know more details of my parents' and grandparents' lives, I can see why the things I write may be valuable, even if it doesn't feel like it at the time.
