Join Priori now, work with users around the world to get rid of busy and ineffective work, say goodbye to procrastination, and re-understand time management. The following is selected from real global reviews: "A very nice App with a UI that is terribly concise and makes people want to finish more plans and then cross it out." "It's no exaggeration to use art to describe this App." "It's the ideal App in my heart!" "I love this simple style, nothing extra." “wow! I didn’t expect that quality. really good interface. ” “Less is more! ” “Науку в массы ! ”(Russian: Theory goes to the masses!) “私の仕事と人生に大きな助け”(Japanese: Very helpful to my work and life.) [ What is Priori? ] Priori is a time management tool that implements the Eisenhower Matrix rule on mobile devices. Faced with endless work and life pressures, Priori hopes to minimize the burden of user “to do list” at the visual and operational levels through an effective but minimalist design language, while using the Eisenhower Matrix rule to return focus to the focus. Above the most valuable things. The important things are rarely urgent, the urgent things are rarely important, give yourself a chance and let Priori do the work with you efficiently. [ How the Eisenhower Matrix matter classified should be implemented? ] Let's take a look at the 4D solution for time management Eisenhower Matrix: 1. First matrix (important and urgent): Do it now The first matrix is the crisis matrix. In this matrix, matters are not only urgent but important. Keeping an eye on the first matrix can lead to stress, exhaustion and other related problems. Covey believes that people who pay attention to the first matrix for a long time will only find relief in the fourth matrix. Because the fourth matrix is neither important nor urgent, humans prefer to do these things. 2. Second matrix (important not urgent): Do it a planned way According to Covey, "the second matrix is the core of efficient personal management." Really efficient people will pay attention to the first matrix, but the second matrix is concerned. In this state, we will focus on opportunities, think in a preventive way, and will reserve enough time to focus on what really matters. 3. The third matrix (not important but urgent): Delegate The main reason why most people find that time is not enough is to take too much work that is not their own. We should realize that it is our busy and blind source. It is best to authorize others to do things in this matrix, or to reduce the investment in such matters through euphemistic rejection. 4. Fourth matrix (not important, not urgent): Don’t do it This thing is a matrix for buffer adjustment. When you are tired, you can adjust your mindset and body through something that is not important and urgent, but if you are always addicted to the fourth matrix, then our output will be greatly reduced, directly causing wasted time and wasting life.
