What do you do instead of TV/Computer before bed?
Exercise can backfire in terms of sleep. A bit earlier in the day and it's great. But not right before bed, at least not in my experience.
How do you think people achieve the goal of 50 books in a year, for example?
I hated going to bed as a child (all that wasted time!) but my parents cleverly said I could read in bed if I wanted to stay up.
I usually fell asleep within an hour or two anyway, and I ended up reading a huge number of books, which served me well.
My wife and I sometimes read together before bed now. It definitely aids sleep.
As a matter of fact I'll put my phone away and get my book out.
Good night! :)
/r/nosurf is a good start (but isn't particularly a high quality sub)
