First, part-time jobs can hone people's willpower and execution. If you go to help others, you will certainly be wronged and suffer unbearable pain. If you can persist at this time, you will definitely gain more than money.
Second, only by doing small things well can great things be achieved. Work can be said to be a very valuable opportunity, because it is the beginning of your success. No one is born successful. They also start from small things and work for others.
