Open Notebook Principle (dmragone.com)

In fact, I have been practicing it since a long time. The Open notebook serves multiple purposes of brain storming your ideas, doing minor calculations, to do list.Sometimes I have loose sheets accompanying my Open Notebook to write down those things that need to be referred time and again and I don't have to turn back the pages of my notebook to look at them. And on one fine day, if you turn back the pages of the notebook, you'll notice the chronological evolution of your idea from what it was at the very first thought to what it is now.
