Albert Einstein once solved a problem on the board:
9 x 1 = 09
9 x 2 = 18
9 x 3 = 27
9 x 4 = 36
9 x 5 = 45
9 x 6 = 54
9 x 7 = 63
9 x 8 = 72
9 x 9 = 81
9 x 10 = 91
Suddenly the room was in chaos because Albert Einstein got one problem wrong: 9 x 10 = 91. All of his students were laughing at him.
Einstein waited until everyone was silent and said:
“Despite the fact that I correctly analyzed nine questions, no one congratulated me, but everyone laughed at me because I answered one question incorrectly. So, even if a person is very successful, people will notice his slightest mistake, and many people “enjoy” it. .”
The only person who never makes a mistake in life is the one who does nothing.
