What can graphic designer do to keep up creativity?

It's a question that I can relate to, but in another way. I am a high school student who likes digital drawing as a hobby, but there is a problem we all encounter. This problem being art block. Nevertheless, art block or lack of creativity isn't a severe problem we can't solve. A key point of getting rid of this problem is by going out of usual. For instance, if you are used to draw cars, why not to try drawing nature instead? Or if you only draw digitally, maybe drawing traditionally will become an option to change the routine. You can also increase creativity by looking through your dreams. Yes, your dreams and find something that sparks your interest/ isn't done before. This can be done by keeping a dream journal. You can also look at children scribbles and give it a new perspective to boost creativity. I personally like taking unusual prompts from people I know. You can do it for both fun and profit!
