One day a School Teacher wrote on the board the following...... 
📝
9x1=7
9x2=18
9x3=27
9x4=36
9x5=45
9x6=54
9x7=63
9x8=72
9x9=81
9x10=90
When she was done, she looked to the students and they were ALL laughing at her, because the FIRST equation which was wrong, and the teacher said the following; 💬
I wrote that first one wrong on PURPOSE, because I wanted you to LEARN something IMPORTANT... 
💡
THIS was for YOU to know how the world will treat you.... You can SEE that I wrote it RIGHT 9 times, but NONE of you congratulated me for it, but you ALL laughed and criticized me because of the ONE wrong thing I did.... 
🔑
The world will NEVER appreciate the good you do a million times, but will criticize the one wrong thing you do.... 👍🏿
So chin up and stop listening to the naysayers.
