Welcome to toki pona!
Some suggestions: Keep a daily journal, in TP. Get a notebook, and every day, write about a half-page of text in TP. You don't have to create original prose or profound poetry, so any text will do. Describe your room, your surroundings, your family, your childhood, news stories of the day. Paraphrase or record from memory an example conversation from Pije's lessons. Write anything, but write every day.
Write in TP, on the first draft. Don't write your thoughts out in English, then translate from there. Instead, think out your sentence in English if you have to, then write a draft translation in TP. Reread you TP, and revise as necessary to polish it up. Eventually, you'll be able to think directly in TP.
