Your question is a very practical one and how I wish that I could answer it in a practical way. Whether it's because I was reading since the age of four and my Soul does not like to do this anymore, I cannot say.
I now read only Spiritual books - books that would inspire my inner vessel and elevate my God-like status. I find them in the motivational and self-help or life-coaching categories, but mostly I go deeper into the esoteric which for me, by the way, is as natural as drinking water.
The Psalms; the words of Christ, Buddha, Paul, Thomas A Kempis, Rumi, Ramakrishna; Sri Chinmoy ... are just a few. I do read the daily papers, but I really struggle with anything else. My inner being simply rejects them and shuts down. Much peace.
