1. One important thing you should first consider when writing a haiku poem is getting the ideas you need to get started. There are a lot of things you can do to get these ideas. You might decide to go for a walk, especially in areas where you can easily get inspired by natural things around. You can study certain seasonal events and get relevant ideas for your poem. At times, reading different examples of a haiku can bring the basic idea you need to get started.
2. Get familiar with how a haiku is written. You can start by studying the syllable and the line structure of a haiku. Doing this will help you a lot when writing your own poem.
3. When you are talking about a subject, make sure you reveal how it feels, smells, sounds, looks, and tastes. This should be done because that's how haikus are written.
4. When describing a subject, use images and descriptions that are not abstract.
5. Always use the present tense when writing a haiku.
6. Go over the draft you've made and read it out loud.
