Summary
The way of the essentialist is to eliminate all that is unnecessary and reduce friction to what remains. This enables increased focus and action on what matters. You are then able to make faster and more meaningful progress to your goals. Design your life such that there is no excess.
By defining a clear purpose you are able to use it to guide your decisions. Most everything you encounter will not be conducive to this purpose. If something is non-conducive to what matters, what is it’s purpose? Will it not be better discarded so you can use the time and energy it occupies elsewhere? You must be aware of the trade offs for your actions, sacrifices are inevitable and should be made ruthlessly. In doing so, you can have a previously unseen abundance of time. Utilize this time with a single focus that aids your purpose for meaningful progress.
In your striving for your defined purpose you must attribute time to both sleep and play. Adequate sleeps allows for high performance when it is required. Adequate play sparks exploration and creativity in solutions.
