One day a teacher on the blackboard wrote:
When he finished writing, he looked back. The pupils was laughing because the first equation was wrong.
The teacher said to them: * I wrote the first equation wrongly intentionally *!
Because I wanted to inform you today of the most important thing:
Most people around you do not care if you do the right thing, even a million times,
But you are a target * for criticizing them for one mistake you made *
Do not be discouraged by the multitude of scoffers
