A good list which is missing some fairly important concepts/methods:
the 2x2 box (important to not important on the x axis and urgent to not urgent on the y axis) which helps splitting tasks in what needs to be done now, what can be (or should be) delegated, what shouldn't be here (not important and not urgent), ...
journals (writing down what you did, what you plan on doing, how grateful you are, ...) / blogs
kaizen method (when you do something and think of a better way to do it -> stop then try it -> assess it and use or reject it -> repeat)
There's many more but I can't remember the rest right now.
