Part time job

A lot of students usually do part-time job. Is it good for us or not? For the advantages of working part time, since we earns money,  we will realize that earning money is difficult. And as the money was earned with difficulty, we think that we should save the money. And in working part time, we will be able to make human relationship with many people and can utilize the spare time.
  But for disadvantages, it will impact one negatively in reduction of time for self-development and personal hobby life, plus for a studying student, it tends to lower the studying efficiency. However, in my thoughts, trying to work in a part time job is not bad. That is why through working part time job, we can build up new experiences which have not been attempted before and one will be able to earn some money.
