There is no second chance to be reborn again. However, if you would be a parent to teach your kid to learn the world, it's your second chance to make a better choice in the simialr situation.
"You shouldn't be so stubborn, everyone is suffering the same issue, why you couldn't be more tolerant?" my classmate persuaded me during the dinner.
"Well, I know that. I am not being stubborn to pursue perfection, what I am doing is finding a solution," I looked straight into her eyes and asked, "you think it's okay because you could tolerate till graduation and never work in academic research again, but how about your children? In your 19-year school life, you learned nothing but obey the rule to get passed. Then would you tell your children to do the same for another 19 years?"
"... hmmm, " she hesitated for a while, "everyone does so, there is no other choice."
"Do you know why there are so many parents crazy about education?" I didn't reject her reply directly but asked another question, and answered it myself, "it's not because the pressure from the society, but the stress from themselves because they don't know how to learn smarter when they are a student, either. They don't know how to foster creativity, so let the kid spend every weekend in the painting class make them feel safe and guiltless."
