Let me ask you a question, do you remember times when you tried to change someone's behaviour? I'm quite certain at some point in your life you have!
When you tried to get someone to do something different, how did it go? What did you say? What did you do? Most importantly how did the person react, where you aware of this or not?
Naturally, I'm guessing it didn't go so well. Firstly, the person probably didn't change. Secondly, things probably got worse as the person became angry, silent, or defensive towards you.
The interesting thing is that not only you might have tried to assert yourself and persuade the person to your way of thinking, but you probably pushed them further away from where you want them to be, right?
It's frustrating, isn't it? The most common communication barrier people use in this situation is giving advice.
You try to send a solution to help the person. You think you are doing the person a favour by giving advice, but all you are really doing is making the person feel frustrated for having received the solution. Are you ready to discover more?
