Interesting question.
A mix of both almost to extremes which may need to both be balanced by yin and yang practices.
Writing can be very yin if you sit alone in a workspace and write. It can also be very yang if you follow classical theory and work out every movement and harmony according to it's standards, or generally think intensely while writing music.
Some physical activity (yang) would help for all the time being stationary, and some time away from writing, free and unstructured, could help to balance the mental intensity (comparatively yang) of writing.
This also gets balanced out with performance though, as it is usually quite exciting and then you have fun and drink (hopefully not [too] excessively) and socialize which is very unstructured.
Learning some qi gong and baguazhang basics would be one way to ensure that you can always add a bit more yin or yang without even leaving your work space if needed.
Be humble, believe in yourself.
