These two categories are collectively called professional lecturers. Generally speaking, the development mode of freelance lecturers is to be internal lecturers first, and then spend some spare time outside to train companies and customers to be part-time lecturers. After accumulating some class hours outside, they have a certain influence, popularity and reputation, and then jump out to be freelance lecturers. The "two similarities" situation is that in other positions such as sales or curriculum research and development in training institutions, you give more lectures and have more information, and you figure out a lot of things yourself, start to try to speak by yourself, and finally become an internal lecturer in training institutions. With more classes and more popularity, you may jump out and become a freelance lecturer. However, in either case, we must do two things. First, the course is very good, with its own unique teaching style and core brand courses. Second, it is not easy to get others to pay for you. The second one is more difficult. The first is to teach the class well. It's not easy at all. First, locate what to teach, what to say, what to say, and what to say well. Combining your own experience and professional knowledge, what can you share with us? It won't be as simple as buying a few books and searching several courseware and outlines online. Students will ask you all kinds of questions, which are actually encountered in practical work. Without personal experience, it is not easy to provide you with a clear solution to the problem. The difference between an excellent teacher and a mediocre teacher lies not only in what you have prepared for class, but in how to answer practical questions raised by students, including case analysis and comments, which requires basic skills and experience. Then look at what you lack, including professional knowledge structure, lecture expression skills, demonstration of new technology application, training demand survey, curriculum development and so on. It can't be created in a year or two. It needs experience and accumulation. The second is how to get others to pay for you. There are two kinds of teaching effects: "applauding" and "winning". Some teachers applaud but don't "call for seats", while others don't. One is the atmosphere and skills of your interpretation of the scene, the practicality of a content and the real help to everyone. Some teachers think that if I speak well, others will pay for me. Why do people have to invite you? Now there are so many teachers, how to stand out among them and become a "dark horse"? You know, even Maotai is advertising itself, and now it is "good wine is afraid of the deep alley" and "good wine will definitely shout". This involves the packaging and promotion of lecturers, that is, how to do marketing? How to find your own unique selling point? Who is my target customer? How to passive marketing? Including setting up your own blog and website, publishing your own articles on some professional platform websites and writing your own unique views, so that more training companies and customers HR can know you and who you are. What is your advantage course? What kind of courses are you suitable for? What kind of customers are suitable for service? And these need to be done step by step, not overnight. When the lecture level is average, the higher the popularity, the faster the "death". After all, training companies and training industry circles are very small, and everything spreads quickly. Becoming an excellent professional lecturer is "sharpening a sword in ten years", which requires all aspects of knowledge, skills and good mentality to stand out and get ahead. After all, the current training market is not as good as before, and the current trainers are not as harsh and demanding as before, growing up in the "picky" of training companies and customers. Firmly believe and aim, go all out and persevere, and you will certainly become an excellent professional lecturer.
