Stop consumption and input.
All the information you receive as input needs to be processed by the brain, thus taking up processing space and bandwidth that could be used by the more important tasks at hand.
How I reduce input:
- I avoid listening to songs that have lyrics
- I don’t use social media newsfeeds
- I don’t have any political opinions
- I stopped consuming news
- I don’t follow religion and religious news
- I don’t process every conversation around me
- I don’t keep up with fashion trends
- I don’t follow series or shows
- I live in places where I don’t understand the language
