Many years ago I was attending a self-development event where there was a line-up of speakers each speaking on their topic of expertise. The room was filled with about 400 participants.
Many could not interest me TBH but there was this one British fellow called Andy who took the stage at a moment. He opened with the sentence I'll never forget. He said: "After my 30 minute talk I will have sold over $100K in courses.
I remember the audience laughing loudly but boy ... After his talk I saw about 40 people in the audience running to the back of the room to sign up for his $5K course! Yeas, they were actually running towards the registration desk in the back of the room.
This man had mastered the art of influencing others so they would to what he wanted them to do!
Friends, this is in my opinion the One Skill you need to master in order to have a great life.
PS: Yes I bought his course too of course but not at that moment, still have it on my EHD.
