What price have you paid for not working hard and how did it go afterward?

If you don't work hard, there are so many costs to pay, for example, if you don't work hard in elementary school, you can't get into a good middle school, if you don't work hard in middle school, you can't get into a good high school, if you don't work hard in high school, you can't get into a good college, and the relationship between them is all cascading, and each stage is very important, and the cost is that you have to pay more now than other people do, and only in this way, later on, you can be better and better!
