Ideas need to be atomicatomic things are self-containedatomic components are specific in content and self-contained. Having these attributes makes it interoperable. and grouping things doesn't create atomic ideas.
When we don't create links atomic links (e.g.
[[school]]), there will be many connections with very little meaning, adding clutterclutter slows us downHaving clutter makes it difficult to find things or gives us less space to do what we need to do. As a result, it slows us down.
Also, complicated things usually add clutter which is why simple is often better.
