This thread is already filled with incredible tools and inspiration. To balance that: learn the art side, not just the programming.
If you're interested in the visual domain learn about image composition, colour and perspective. There is milenea of knowledge on these topics. For audio work, learn about music theory, or for atonal areas sound design and exploration of noise. For motion, explore material on animation and film. This extends to poetry, fashion, architecture and the multitude of other domains that let computation and creativty combine.
These will all give you a tour of aesthics and techniques that you can then use to help shape yours. You can then learn (or build) the generative tools that help you realise this. This doesn't need to be a sequential process, but don't just focus on this last step as you'll miss so much of what may be influential to your work.
