Minimizing friction has been the game-changer for me. I don't avoid easy-to-do things, I just do them. If I can pre-load getting rid of friction I do.
For example, a meal plan generator was an expense I justified because it grossly simplified meal-planning and shopping. Removing that bit of friction made me much more likely to stick to my plan to more healthily.
And also reducing as much friction as possible. For me, that means, reduce temptation to style and ultra minimal note categorization.
• New Note in my OS's default, no-frills note app.
• Start typing.
• Done.
I can always search it later with keywords. Getting it out of the brain is already an immensely feeing act, anything else is bonus.
(I do some post-notetaking categorization but it's not systematic and I allow myself to just leave it in the default bucket of uncategorized notes.)
