Yep point 1 I think is the most important, but if you don't have the luxury of an office at home, having a start of work process, and an end of work process is really important e.g. at end of day, close laptop, put away in a drawer, and tidy up work paraphernalia, then sit down and have a cup of tea while reading a book. It mentally bookmarks the start and end of work, and allows your mind to reset from work mode.
