Practice more and consume less. When you watch content whether it be mass entertainment, pornography, whatever, your brain spends less time creating things in your mind and more time just taking already existing ideas. It's like the idea equivalent of a drug addiction, your brain doesn't produce enough imagination when it's offloaded to others. So just try and make stuff yourself, channel your creativity by just sitting down and trying to make something, and do it more and more to improve while spending less time just mindlessly looking at mass entertainment
