I think this topic often happens to students including me. The matter happen there is certain reasons.
Procrastination comes when we think a lot about what we need to do and how difficult is, we start thinking of multiple other thinks we can do or have to do before starting the work. This causes a lot of frustration, anxiety, stress and a lot of wasted time.
The fear of failure is one common cause of avoiding doing a task. We think of the different problems and weakness we have and how complex the work is. As we think in our mind the complexity of the project, we start thinking of the different reasons why we cant accomplish it and the many other things that you need to do it.
Doing it in the last minute, most students and even employees let their homeworks or work for the last minute, they thing of how much time left they have, so they put the work aside until the time comes. What happens is that you end up doing very little work at the last minute or very poor job.
They dont think of the time necessary to accomplish a task successfully. Most people just think of what are the task that they have to do, but they dont plan what things they need to do and resources they need to accomplish it.
Another cause of procrastination is thinking that you have to be in the right mood at the right time. That is a real time waster, you might not feel like doing a work or you might have other personal problems that you are thinking about so you set aside your work. That is wrong you need to start your work now, no matter in what mood you are, the more involved you get into your work, the less you are going to think in other problems.
They usually do not say no or cant avoid chatting with a friend or any other communication that prevents them from finishing his important work. You have to be aware of this problem, because can be the cause of low performance and bad grades.
To avoid procrastination you need to apply some techniques that can help you and look also for the help of your parents. For example, you need to set aside a few hours a day to do your homework, use 2 or 3 hours a day to get done your homework and focus on it, turn off the cell phone, the chat, the email and dont stop until you have finished your homework.
Procrastination in teenagers could be for many different reasons, it could also be low self esteem, lack of motivation, complexity of the work, lack of interest, anxiety or even depression. If you want to do other activities, do them before the schedule of your homework, but when you are ready to begin at your set time, it doesent matter anything else just focus.
