Ways to make a list

On paper
Yellow 5x8" legal pads (I have dozens floating around my house)
Spiral bound notebook, like in school
Post-it notes
On a napkin
On the back of an envelope
On a whiteboard ("do not erase!")
On a computer
A text file
The iOS Notes app
Emacs orgmode
In the cloud
Bulleted list in a Google Doc
Rows in a Google spreadsheet
In a long-running self-addressed email draft (like Shane does)
In a wiki
Dedicated list-making mobile app, such as Things
Bulleted list feature in Notion
