on writing blog posts

It happens to me all of the time. I'll see a picture and think a seemingly profound thought. I'll want to write about it, and then life happens. When I finally get a moment to sit and process, the good idea for a blog post has drained away. I wonder if learning to paint might help, that way people can take whatever they want from the picture in my head. Instead, I sit in pity wondering. God has shown me so many beautiful things over the years, and I want to share. Why don't I? Anyone have a good answer for this?
