I think I prefer. It helps me cut with the mental load of the day, and helps me go to sleep faster, even with a technical book (except on rare case when the book is about my work and get my gears going ;) ).

Reading in the morning is impossible for me, I have to manage three young children go to school and I go to work right after that.

I'm not an early bird too so it doesn't help ;)

But I do believe that, in summer, going out early, reading a book outside when the sun has just started to get up, might be something amazing :)
