TIP #3:
Use a Naming Convention

It’s helpful if you can see a folder—on any platform, on any device—and instantly know which of the four main PARA categories it is in.

I like to use an informal naming convention to make this possible, such as:

For example, these are immediately recognizable as projects (because they start with emojis):

These are clearly areas (because they are capitalized):

And these are resources (because they are uncapitalized):

These naming conventions also have the benefit of working across any platform, since they require only the most basic text characters.
