Decrease the noise
Simplicity is removing what does not matter until only the essential remains.
How I use it
When life feels confusing, I look for noise - things to cut before I look for new solutions.
Example
Fewer tabs, fewer inputs, fewer random commitments, fewer people's opinions and fewer distractions between me and the thing I need to do. Last months been busy a lot doing everything. But now I'm cutting things out and focusing on the essential. Identified several points that were not essential and cut them out. Main ones are: late night going out, dating, smoking.
