Journaling is nice for some layouts. But poetry can be used quite effectively, as well. It's even better when you do it yourself. Now, not all forms of poetry have sentence-like structure. Some forms are just adjectives. Two very easy forms of Poetry are:

The Acrostic Poem. You can create an acrostic poem by thinking of a single very important word for your layout - it can even be your title. Then, think of a word, or a phrase that starts with each letter in your word. An example could be:

Lovely
Ornate
Resilient
Anonymous

Another form of poetry you can use is called a Haiku, which is an ancient form of Chinese poetry. These poems are based on the amount of syllables in each line. These poems contain 3 lines. The first line has five syllables, the second line has seven syllables, and the third line has five syllables again. You can do whatever you want with these poems, though. An example could be:

Life has many roads
Traveling seems bittersweet
Choose the wisest course

My poems aren't very good, but you get the general idea. Now, go try it yourself.
