all kinds of calls, seeing all kinds of people, handling all kinds of things, it doesn't matter, as long as you do so many things for the same purpose, your job is valuable. Although scattered, it will definitely test your ability. Only one thing every day does not allow you to learn time management. If you do 10 things every day, you must learn time management. Only by discovering your own shortcomings at work can you make progress. If I think of my
