When I started working, I worked as a teacher in a higher vocational college. In addition to having 20 lessons a week, I also had to be a counselor. Due to the poor quality of the students, the school learning atmosphere was not ideal, and the classroom teaching was all about not learning Of students, I will have a full sense of frustration after each lesson. Every week, I really feel like the entire person has been hollowed out. Later, I resigned decisively and changed to a more preferred job. The feeling of hollowing out is gone. The main lessons of the "I" story are:. ['Acquiring a sense of accomplishment is often a matter of personal preference.', "If you can't change reality, try to adapt to it.", 'Instead of consuming self-confidence in frustration, choose another life.', 'Only by doing your favorite job can you avoid frustration.']
