Stop comparing yourself against other Real Estate agents. Keeping focused on your skill set and what you can bring to the table can maximise productivity and improve the way you present yourself to a client.
When you assume without knowing many agents create a whole load of emotions that are eroding their confidence and this is also increasing worry and stress for them. What are you telling yourself that could be derailing you?
In real estate, there are more ways than one to move your client. If you want a client to feel a certain emotion, then you need to bring that to the conversation. It's less about being polite, avoiding sounding pushy or demanding and a whole lot more around the energy and emotion you bring with you. This way the clients feel the impact of the conversation.
