The basic definition of management is coordinating activities to achieve an objective. If you think about it, all human activities have an objective: making a meal is to achieve the objective of not being hungry anymore, getting dressed and putting on shoes achieves the objective of being ready to go out.
Every activity which we undertake in our everyday lives requires planning, controlling and organizing, and these three activities are the foundation of the management process.
In the same way as a manager in a business will, for example, plan the logistical operations of a company—making sure that all the required components are in stock and that all the machines are in good working order, an individual must plan the logistics of daily life, from meal planning and coordination of family members' schedules to planning family events and ensuring that the house is kept clean.
Management is a universal function in all human activities and our brain is the manager. Every simple activity that we do is a culmination of a number of steps taken in an organized manner. For example, a simple activity like typing an email requires a number of activities. Our brain thinks what we have to write, the signals are sent to our eyes to check what we write and to our hands to type. The adequate amount of energy will be used by fingers to type, eyes to read and brain to verify the content. Without the simultaneous management of these operations (and a large number of other minor simultaneous operations), the successful execution will not be possible. When we eat, we manage the quantity of food we eat as a whole and in every bite; the rate or velocity of food ingestion is also managed.
Basically all human functions and activities are a management of our resources (body, energy, etc.).
