It is key to think over and learn when we have and solve questions to avoid the similar mistakes again. Firstly, during the system development, if I don't understand the task to begin the program, the functions of the program often will not be perfect. I also waste more time and energy, so, I think you must understand the task, system flow thorough and know what's what before you develop a program, then you can carry out to develop the software and save time. Secondly, you must grasp the all kinds Knowledge, research the real work, consult the management and operation person on field, all above will help you adjust ideas and solve questions. Thirdly, it is important to learn from others. After all, one's energy and practice is limited, we should use others'practice better to achieve unexpected results.
