One day, this young man ushered loads of dozens of books into a 7-storey office in a college; when he was carrying those books waiting in the elevator, a security guard in his 50s approached him and said: "This elevator is for professors and lecturers, others are not allowed to wear this elevator, you have to go by the stairs!"
The young man gave an explanation to the guard:
"I just want to take this car book to the 7th floor office, it's this campus order book!"
However, with the violent security guard said:
"I say no you should not, you are not a professor or a lecturer, you can not use this elevator!
The two men argued long enough in front of the elevator door, but, the security guard still insisted not to budge. In the mind of the young man thinking, if you want to carry out this full car book, at least have to go back and forth 20 times more to the 7th floor, this will be very tiring!
Then, the young man could no longer contain this troubling security guard, and as soon as his mind flashed, he moved the piles of books into the corner of the hall, then walked away.
Afterwards, the young man explains the events he experienced to the boss, and the boss can understand it, as well as submit a letter of resignation to his boss, and soon after that he went to the bookstore to buy materials for high school and reference books, while shed tears he swore , I have to work hard, have to get into college, I will not let anybody harassed again.
During the six months before the exam, the young man studied for 14 hours every day, because he realized that the time was not much, he could not stand back, when he was lazy, in his mind always imagine the insult security that does not allow him to use the elevator, imagining this discrimination, he immediately spurred his spirits, and doubled his hard work.
Later, this young man finally managed to pass into one of the institutions of medical science. And now, for over 20 years has passed, the young man finally managed to become a clinic doctor.
The doctor reflects for a moment, then, if it were not for the security that deliberately complicated him, how could he wipe his tears from the insult, and stand up boldly?
He has been indebted to the insulting security!
It's amazing what one act of ignorance can do to open up doors and to influence your perspective in a positive way!
