Is it a simple psychological function, or does it have its principle?

It's natural to take pains and be sweet, which is in line with the philosophical principle of changing from quantitative change to qualitative change. Of course, you should also believe in taking pains and be sweet psychologically. "Study hard, be good at learning and be eager to learn", "If you refuse to bury your head today, how can you look up tomorrow", "There is no way out, leaving a way out is a dead end", "Fight for autumn, winter, spring and summer, and win your life without regrets", and even borrow the slogan "Reading three thousand Taoist scriptures, changing your life against the sky" in "Selecting Heaven" as a slogan for intense students. When you see these slogans, you will definitely not.

There are many people who complain about why they work so hard, what they can get from hard work, what kind of hard work they choose, and what kind of life they choose. In My First Half of Life, we see that people in the workplace often work overtime. When Xue Zhenzhu said to Tang Jing, "You have money and the ability to make money, but Jun Jun is different. She doesn't have that ability. You let her help. Indeed, if you want to have more room for promotion and make greater progress, you need to make more efforts. Don't say who is richer than you and who enjoys it more than you. You should also see that they actually work harder and take more risks. There are still many people who suffer for the sake of a better life for all of us. Every time the submarine soldiers go out to sea to perform a task, it is a life-and-death test, but they all love submarines so much that they will do whatever it takes to complete the task. Of course, we must be full of hope for the future. I believe that what you are suffering now is temporary, and you will certainly gain something one day. However, it is impossible to get a lot without eating any pain.
