Ask HN: How to regain the ability to read with focus and learn

I have noticed my own decline in terms of attention spans, and (in)ability to read long-form text online or offline. This leaves me with a disaatsifaction and I would like to rebuild a good habit cycle.

Curious to know if any of you went through the same and managed to recover from this rot. What worked for you, and any thoughts and learnings you might want to share.
