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.

Touch the keys An Article by Rach Smith rachsmith.com In his course Being Productive: Simple Steps to Calm Focus, Kourosh Dini emphasises the importance of taking a moment to “be with” the work every day (or however frequently you need to tackle a project). “Being with” your work is to be fully present and intentional about that activity and doing nothing else. This idea was inspired by Dini’s piano teacher, who encouraged him to sit at his piano and touch the keys every day. Even on the days that he felt he had no time or inclination to practice. Sometimes touching the keys would lead to a good practice session, even when he didn’t feel like it would before he actually gave it a go. Just like Dini, I find that once I give the task my full attention and be present, the actual doing of it turns out to be much easier and more enjoyable than my mind had been expecting. As usual, the resistance to getting started is far more uncomfortable than actually doing the thing. To pick up my pen productivityworkcreativitypractice
