Successful operation is a process of giving an expectation and continuously exceeding it. After several times of such results, trust will be further enhanced. Of course, even though there are multiples of strong recommendations, the final product is disappointing. If it is not as expected, users will be disappointed and will no longer trust it. If there is a new deal, if you really want to create value and make mistakes, you need to apologize positively. Correct, not quibble. I don’t think it’s okay to use a little effort in marketing. Good things need to be boldly shouted out. If you don’t dare to shout out for something you make, then maybe this thing shouldn’t be made.
