The problem is rarely that we have too little to read. It is that we have not built a shape around reading that protects it from everything else. A quiet reading life begins with subtraction.
Choose fewer inputs than you can handle. Keep a short list of writers you trust. When you find something worthwhile, stay with it longer than the platform encourages. Copy a sentence by hand. Return to it the next morning.
The goal is not asceticism. It is permeability of a better kind. You want to be changed by what you read, and change usually requires a little silence around the thing itself.
