"People who are working hard talk about their hopes, and people who are lazy talk about their dissatisfaction." by Yasushi Inoue
I don't really like the word "effort", but I can use this word, and I can use it very effectively.
Let's put these words on the wall of our house. And if you have a family member or friend who is dissatisfied, dissatisfied, or complaining, point to the words posted on the wall and say:
"Are you lazy?"
We guarantee that it will be extremely effective.
