Let’s quickly go through each section:
The 3 most common areas for ideas are:
1 - Shower
2 - Walking
3 - Bed
Now with this fact in mind, you should then approach ideas in these areas as sacred artifacts.
Here’s how you maximize what you have in each area:
1 - if you have an idea in the shower then use a memory technique (ex: mnemonic or method of loci) to be able to retain that idea until you get out of the shower and get a chance to write it down
2 - if you’re walking
and have an idea, immediately add it to your favourite notes app (I recommend Notion
or Apple Notes)
3 - if you are about to go to bed, always have a small notebook and pencil next to you. That way when you have ideas you can easily jot them dot and then review them and add them to your digital notes when you wake up.
Now that you have an idea you need to have a system for categorization them.
