Immerse yourself in something. Pick a topic that interests in you and then get a book, an audiobook, youtube lectures, a video game and related food. For instance, I once played Assassin's Creed: Blackflag. Set in the golde age of piracy. So I was playing this game, listening to audio books and dramatized audio plays such as "Treasure Islands", listening to lectures about the historical age of piracy, eating coconuts, daydreaming about being a pirate with magical powers and his own Carribean cave with sexy girls etc. Or, once I read a lot of Sherlock Holmes novels and then bought English Breakfast tea, got some audio version of it, went to Second Life and just enjoyed looking at some Victorian-ish environment while listening to Sherlock Holmes novels and drinking tea, then reading a bit about the British Empire, etc. Or you pick an artist you like and immerse yourself in his work. Last artists I did that with was Richard Wagner, then you read his writings, the librettos, listen to different recordings of his operas, watch documentaries about him, etc. Just pick something you like and that could interest you, no matter if it's challenging or low-brow.
