What enlightenment does the story from Sao to climbing Sao give us

Scientists have done such an interesting experiment: put a flea on the table. As soon as you strike the table, the flea immediately jumps up, and the jumping height is more than 100 times. Then, put a glass cover on the flea's head and let it jump. The flea jumped back when it hit the glass cover. After doing this many times in a row, the flea kept the height below the top of the lid every time it jumped. Then gradually reduce the height of the glass cover, fleas always jump lower after hitting the wall. Finally, when the glass is near the table, the flea can't jump any more. The scientist removed the glass cover and knocked on the table again, but the flea still didn't jump. At this time, the flea has changed from the original "high jump champion" to a "crawling flea" who can't jump. We know that jumping is a flea's natural ability, but when a flea becomes a "crawling flea", does it lose its ability to jump? Of course not. The reason for this is that fleas have a negative mentality after hitting the wall again and again: I will hit the wall again if I jump high, and actively reduce the jumping height in order to adapt to the environment. Repeated setbacks slowly devour its self-confidence and become accustomed and numb in the face of failure. What is more sad is that the glass cover on the head has long since disappeared, but it has lost the courage to jump again. The desire and potential for action are stifled by their own negative thinking patterns, which scientists call "self-limitation". Many times, like this flea, we humans will encounter many setbacks and failures in our study, work and life: when we need help, we may be rejected; When we make repeated efforts, our grades may still not improve; When we want to do something well, but fail to do it well, we may be laughed at, discriminated against or even denied by others; When we try to prove ourselves, we may hit a wall from time to time ... These frustrated failure experiences often make us doubt our ability, lose confidence in ourselves, lose our enthusiasm for progress and courage to overcome difficulties, thus limiting our potential and making it impossible for us to succeed in our career. This is the result of "self-limitation". Students will inevitably encounter setbacks in their study and life: for example, failure in exams, abnormal performance in activities, and low skills in some aspects ... Coupled with the objective evaluation of teachers and parents, these will easily lead to their own mindset of "I couldn't have done it originally", so they laugh at themselves, make themselves self-defeating, break the jar, give up their efforts and turn themselves into "crawling fleas". In order to avoid this phenomenon, we should fully understand our own potential, believe in ourselves, don't be afraid of failure, keep in mind the adage that "failure is the mother of success", constantly sum up experience from failures and setbacks, learn lessons, make constant efforts as the driving force of struggle, and resolutely make unremitting efforts towards the goals we set. Take off the "glass cover" on your head with "I can do it" and break through "self-limitation" with firm confidence. I hope it helps you. If you are satisfied, please adopt it. Thank you.
