Thanks for your post which has become a very valuable and full of ideas guide for songwriters .
Here is how I do it:

1. I write a saying, sentence, something I or someone said and it is worth remembering.
2. I shuffle the words to make a rhyme out of it, many times it’s all it takes, sometimes I use synonyms to achieve it. You can rhyme a whole paragraph of a book that way through a little text modification.
3. I was most successful at that using Facebook posts published just to myself. If I get stuck and the song doesn’t develop I leave it and usually get inspired again by my memories reminded by Facebook next year etc.
4. I was really inspired and started believing I can do it by rappers (I prefer rap music without bad words🎸), I could see so many people writing texts, expressing themselves.
   I hope this will help you and inspire you to use things most natural and working for you, you are a celebrity/important enough to express yourself and be heard and contribute.
   Please follow my more detailed post on that I am going to write soon. All the best! 🎤🎸
