What are the most important things on your list? In general, you might decide that work/school tasks will outweigh social and house-hold chores, though certain outliers may exist. You've got to eat and bathe, for example, though laundry might be able to wait another day while you finish an important work project.  Decide on a few different levels, maybe three, to rank the different tasks and criteria on your list. High, medium, and low importance tasks might be the best and simplest way to start ranking the importance of things on your list. Be judicious in deciding. You can also use colors to rank the items on your list. For example, you could use red to identify important or high priority items on your list, orange for items of medium importance, and yellow for items that are not pressing at all. Consider upcoming deadlines and your ability to work within those deadlines. What needs to be done the soonest? What needs to be done by the end of the day? What might you be able to buy a bit more time on? It's important to consider the length of time it takes you to accomplish each of the tasks, maybe even assigning a set time to certain things. If you consider it a priority to exercise every day, but you've got a crazy amount of work to do, give yourself an exercise cap of 30 minutes and find somewhere to fit it in. It might be critical that you get something to post-office by the end of the day, but this isn't a terrifically difficult task. Rank everything on your list in terms of its difficulty so you'll know how to situate it in relation to other tasks. It might be effective to use levels like Difficult, Moderate, and Easy to rank them, rather than trying to judge them in relation to one another. Don't worry about putting them in order before you've given each item its own rating, if it's helpful to do so. Put at the top of the list the most important and urgent tasks that will require the least amount of effort to try to maximize your work in the time you've allotted for it.

TL;DR in Vietnamese:
Xếp loại theo tầm quan trọng của từng nhiệm vụ. Xếp loại theo tính cấp bách của từng nhiệm vụ. Xếp loại theo độ khó của từng nhiệm vụ. So sánh toàn bộ các nhiệm vụ và sắp xếp theo thứ tự.
