I'm not sure it's a good thing, dwelling on the past, but people who blog have an opportunity to view their past in a unique way. More so than people who keep a journal or no records other than photos. Bloggers capture words as well as images, snippets of your thoughts at that precise moment of typing and the words may be different to what you put in a journal. My journal is for my eyes only, so I feel comfortable throwing in the odd swearword or cuss at a situation but I would never write that way here.
My old blog tended towards the 'warts and all' approach, but when I found myself alone in the world and had to begin again, I pulled back from sharing so much. What was lost along the way, was the poetry of my life. I'm amazed at how much I've changed and I need to reconnect with that part of my soul, so there may be some flowery descriptive pieces dropping in from time to time as I explore the beauty once more.
