Criticism Vs Congratulations

One day, Albert Einstein began to write on the board:

9×1 = 09
9×2 = 18
9×3 = 27
9×4 = 36
9×5 = 45
9×6 = 54
9×7 = 63
9×8 = 72
9×9 = 81
9×10 = 91

In the classroom, a lot of teasing was made, because Albert Einstein had made a mistake. Since the correct answer for 9×10 is 90. All his students laughed at him. So Albert Einstein waited for everyone to be quiet, and said:

Despite having got the 9 questions right, no one congratulated me, however when the only one failed, everyone began to laugh, that means that despite being very successful, society will notice your slightest mistake and make fun of it, don’t let a simple criticism destroy your dreams
