The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

Eyes on the ground A Quote by Akira Kurosawa www.youtube.com When you go mountain climbing, the first thing you’re told is not to look at the peak but to keep your eyes on the ground as you climb. You just keep climbing patiently one step at a time. If you keep looking at the top, you’ll get frustrated. I think writing is similar. You need to get used to the task of writing. You must make an effort to learn to regard it not as something painful but as routine. writingexperienceskill
