How to put yourself in various moods to get inspired?

How do people manage to put themselves in various moods depending on the topic? I am a rookie writer and am about to finish my first solid draft, but my issue is that I don't have an inspiration as to write any future books. Writing from an inspiration feels much better and results in higher quality. My mind usually follows the mood of the environment I'm in, so various environments can influence my future creations, but I don't know how to put myself in a specific environment without actual change in environment.<br><br>&#x200B;
