Read a lot of poetry. If you want to write poetry, start by reading poetry. You can do this in a casual way by letting the words of your favorite poems wash over you without necessarily digging for deeper meaning. Or you can delve into analysis. Dissect an allegory in a Robert Frost verse. Ponder the underlying meaning of an Edward Hirsch poem. Retrieving the symbolism in Emily Dickinson’s work. Do a line-by-line analysis of a William Shakespeare sonnet. Simply let the individual words of a Walt Whitman elegy flow with emotion.
