So you want to learn about typography eh?
Well if you do you came to the right place. First pick a poem that you think you can make look a little realistic or make it look like its alive or real. Then you have to pick a font you know will fit well witb your poem. That's the first part. After that's when the fun starts you get to play with animation timing all sorts of stuff but remember make everything sort of themed the poem. After that point pick a background and a colour and your ready to go.
