Computers and electronic documentation are progress, because it is so much easier to interact, communicate and work together without resorting to the services of carrier pigeons. However, it can be noted that it is not a fact that electronic documents are more environmentally friendly, for example. Even if you refuse to analyze the production, operation and disposal of used devices, it should be remembered that you need to spend a ton of coal (in equivalent) to transfer one DVDRip. So being free turns out to be controversial, but that's not what I'm talking about. I'm talking about the glorious properties of plain paper.
You can entrust a lot to paper, as many generations of our ancestors did. At least she is definitely able to withstand a simple to-do list, which is not bad. The list, as well as much more, can be combined into a pocket organizer, and for sweeping planning, print an empty calendar from Outlook. You can also organize GDT without a computer or remember the (simple and convenient) method of "circles" and "crosses" described by us.
In order to make the list more universal, so that it helps to work with a large number of tasks, and just be more convenient, more than one system was invented. In particular, you can use Auto-focus of the first or second versions for personal needs, and if you need to work as a team in addition, you can remember about tomato time management.
But if you think that the paper is just a list, you are mistaken, for example, you can build Gantt diagrams, feeling like a real project manager. In addition, paper tolerates a lot « and therefore you can draw, write, cross out and connect in any way at a speed that is hardly possible when using a computer. In particular, I would recommend starting building your global plan on paper.
Nothing compares to the simplicity, reliability and accessibility of a pair of paper and pencil. One thing is bad — there is no indexing and backup storage. However, this can also be solved — scan notes in Evernote here's a copy available from everywhere, and text recognition may be useful to you.
