Feedback vs Positive words

2016/9/25 Feedback vs Positive words

The book "Managing oneself" by Peter F.Drucker told that feedback is the only way to managing ourselves.

Without right feedback, positive thinking is no use for success.

# I sometimes tell the words "It's OK!"
It's wrong.
##I am NOT OK.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
