Setting priorities entails categorizing a task according to importance, urgency, preference, or any other variable you like to associate it with to achieve work efficiency. It also increases your focus and concentration on your personal goals. Setting priorities help you create a vision for yourself — knowing what you want to do for the rest of your life. It makes you more self-aware of your strengths and weaknesses, hobbies, time management, and knowing which of these we value more and which matter to us more. Then our time wouldn’t have to be wasted.
