This spare time can be well used, such as cultivating personal interests and turning this interest into money-making skills. Just like one of my high school classmates, he didn't learn art well in high school and retailed for a year for various reasons. During this year, she had no time to study hard and make full use of her spare time. She learned from a chat the other day that the way to make money in her spare time is painting, painting that kind of low-tech oil painting. She told me that even a child can draw that kind of digital oil painting and find the corresponding one according to the numbers on the canvas. Because there is no time limit, she has cultivated interest without delaying her study. I think this part-time job is good, and it is also good to earn a month's pocket money by painting a painting.
