Personal journals maybe as informal or formal as you are. Unless you allow someone to read your journal, no one will criticize your grammar or spelling. A personal journal is a place to reflect your heart.
My great grandfather's journal, kept during the Civil War from 1858-1895 was a personal journal that is a priceless record of history. We inherited the original manuscript and were fortunate to be able to decipher his looping cursive hand writing and have the journal published.
Your journal of experiences is an excellent reference for later publishable manuscripts. Your journals may turn into memoirs, or be the basis of fiction.
My novels are spiced up with some of my journals!
I don't like to write in those fancy store-bought journals. I make my own. I learned the art of book binding from library books and delight in creating distinctive covers. The large book is a drawing journal with a cover of birch bark and moss with a coating of sealer. The yellow banded book has a cover of hand made paper with marigolds. The smaller cover is a fern mounted on a strip of paneling. Each book contains pages and is bound.
I will be blogging a travel journal within the next few weeks. My summer plans are to travel to California to visit my youngest son and my cousins. Later I'll meet up with other missionaries to travel to Alaska where we will again volunteer at camp and churches.
The internet is often unavailable, so my blog posts may be irregular. I will also keep a computerized daily journal and of course take photos.
Join me on my mission trip!
