1, be sincere. If you don't believe in yourself, you can't convince others. Sincerity is the spirit, and it will have incredible power to protect you. Just like driving a car, we should believe that cars can bring us convenience.
2. You must understand. Understand the meaning of classics and ancient books.
Otherwise, when people ask you questions, they will be tongue-tied and make people laugh. I see what's on the table, believers. You can understand whatever you ask. It's like driving a car. You know everything, you can drive an Audi, and it's very good. It's impossible not to drive a Santana.
3, be sure to do it. "example is better than words." If you don't do it yourself, believers will lose confidence. Be careful what you say and do. Walking on thin ice. Just like driving, drive carefully.
4. You must achieve something. This achievement is not necessarily perfect. To put it bluntly, it means "having two brushes". There is no achievement at all, and it is not convincing. Just like driving a car. When you are on the road, people will know at a glance that your level is unusual. Save it not to show off your skills, but to persuade others to preach to yourself.
As for how many people can listen to you, it depends on fate. There was this karma in the past. I came back to hear you say that there was no karma in the past, so few people came. This also happened in ancient Dade. The lecture was good, but only seven people came to listen.
I wish you early success.
