I am doing the test on the wireless module that I purchase online. I need to weld board to connect my wireless module and the singlechip. However, I am very inefficiency and I haven't finished the work now. I need to think about why. Firstly, I don't believe in myself. When I first get the task, I think too much. I doubt if I can finish the task in time. Once I think I can't complete it, I may change my behavior unconsciously. So when you want to do a thing, you must have a positive attitude and avoid the negative attitude.It really can affect your action. Secondly, I always put off the things I am going to do.It has something to do with my study method. When I come across something difficult to do, I will delay doing it rather than trying to solve it in all kinds of ways.  It may be my bad habit and has been formed for several years. Thirdly, I want to say about the environment. I always believe that the environment has a very important effect on people. When you want to think about something quietly, the environment may not allow you to do it. For example, when I want to make the summary in the lab, my friends may speak with each other loudly and I can't concentrate on what I am doing. Maybe you would say we should try to get rid of the disturbance by ourselves and put our heart into what we are doing. But good environment can really make you promote very quickly. Maybe there are people who are unaffected by the environment, but believe it or not, most people can't do it.  We all need good environment to improve ourselves.

        At last, I'd like to tell about the modification. When we come across something that makes us unhappy, our moods may be very bad and we don't want to do anything. It may affect our normal plans and gives ourselves excuses not to do. We must modify ourselves in time and make ourselves become more and more mature.
