To restore peace of mind, life and work must be simplified. The book synthesizes it in a phrase: "less but better". Essentialism is a discipline that helps to identify what is absolutely essential and eliminate what is not. It is about directing one's own existence through free choices, dedicating time to thinking, being clear about one's mission, finding one's talents and not dispersing oneself.
The author, -English- is a leadership and business strategist. In 2012 he was named a member of the Young Global Leaders Forum. Most of the examples he uses are from his business experience, but they can be applied to virtually all areas of one's own business. The guidelines he suggests are very clear and practical.
Some topics that I find of special interest: daily routines as a way to expend less energy and achieve desired goals; how to say no to the irrelevant things and set limits; the primacy of family for a business person; the freedom that comes from concentration; the role of play; being an essentialist requires "metanoia" and leads to happiness.
The style is simple and enjoyable. I highly recommend it. Especially to those who feel overwhelmed by so many activities, to those who do not know how to organize and to those who find it difficult to concentrate.
