1. Friendliness and Congeniality
I think the most important characteristic of a good teacher can have is to be friendly and congenial with his students.
2. A Good Personality
A good teacher has a very good personality; there is no second thought about it. Students always get attracted to teachers with good personality which leads to better communication, understanding, and ultimately good results. Everyone can have a good, decent, likable, and presentable personality. Just dress sensibly well, smell good, and be a little gentle and kind. That's all.
3. Deep Knowledge and a Great Education
Another important characteristic of a good teacher is his knowledge and own education. There is a saying that 'a teacher is only as good as his knowledge is.' After all, he is doing a teacher's job, which is to teach. If he himself lacks in the knowledge of a certain subject that he teaches, he is never going to make a name for himself. So, sign up with only that subjects which you have really good expertise; and it is a moral duty too. Otherwise, it is not worth it.
4. A Good Communicator
One of the very important characteristics of a good teacher is his communication skills. He should be a very good speaker. This characteristic will provide benefits in several ways. For example:

If his communication skills are good, he can convey his lectures with better skill and results.
If he is a good speaker, his class strength increases automatically. People love to hear a person who he can speak well enough. There is always a shortage of good speakers in the world ;)
