For an employee, how to arrange your work time effectively is the important key to decide whether you can get success or not. The word “effectively”, means you should do a lot of work and make it perfect in limited time. Make use of the most of your work time.
We can set an example, when you enter or are on the way to your company at a regular morning, all of things that you should do during this days should be shown in your mind. You can list those by priority. According to this list, you can know what you should do. Paste is on your desk so that whenever you feel confused you can see it.
Meanwhile, you should put your emphases on the time. Do a task you should do on time is an essential point. By the way, you can add “Expect Efforts” and “Result Efforts” items behind your task list as backup items.
The most important point that you should concern is that gather yourself together to do a work. Most of people want to have a comfortable working status, for instance, they would like to listen to the music or chat with other people by doing a work. That is not a good habit even if you are listening light music or are chatting on important topics. I don't mean you should ignore all of important things during your work time. Just if you want to do a thing, do it.
Perhaps you will say it depends on the real time. But all of above is a direction, we all know that. List all of your tasks in one day, plan the time and record it, do it on time, and put yourself on it. Just follow it day by day if you want to succeed in your job.
