Using things that I have read or been taught that have helped me I will put in this page.
LISTS: To make a list more challenging try adding the alphabet as part of the topic. So if my topic for the day was 'food,' Before starting your time write down A-Z then when your time begins name a food for each letter of the alphabet. (A-pple, B-anana, C-arrot, etc)
WRITE IT DOWN: Whenever you have an idea no matter if it's just a word that has a different sound or certain flow to it or if it's a whole sentence; write it down, record it, whatever you need to do before you lose it. You never know when you will be able to use it in your work.
MAKE TIME: Whether it's everyday when you get up or once a week, make time. I have found that having a consistent time helps. You may not get something you love every time that you write but stay persistent and eventually your heart will connect with you pen and you will be rewarded.
