Personally, I think that the biggest change after learning "Psychological Course and Leadership Speech" is the change of speech mentality. In the past, I was afraid of making a speech, making mistakes, making a fool of myself, being laughed at, being disliked by others, and not being recognized by others ... After being taught by Mr. Sun Jian, I understood that the true meaning of a speech lies in giving. A real speech doesn't need to be well spoken or praised. The most important purpose is to make the contents and ideas of the speech useful to others and share them.
Speaking with leaders is a course worth learning, and Mr. Sun Jian is also a respectable teacher.
