I am reading a book with tips about creative writing. One of the key points is that you need to write every single day. It has a few exercises or tips to diversify the writing which will help you make progress. I love that idea and am following this. I am a beginner so I just started with this practice to get me up to speed. Now I was thinking about something... I always had the idea of creating my own world and am constantly thinking about that world and making up stories in my mind. Would it be good if for my daily exercises I just write about that world. For example I could describe a character, place. Write up some laws of some countries,... Maybe I won't use those items in my stories but it will not only help me in my writing, it will also help me in the development of my world as I focus my writing on it. Would that be a good idea?
