This habit is all about listening
Always try to understand what the other people want and need before you begin to outline your own objectives.
Listen carefully before you engage in objecting, arguing or opposing what others are telling you, listen carefully and think about it.
Exercise this habit by putting yourself in the other party's shoes.
This habit, as well as all the others applies to any type of relationship, personal or business.
Remember to always understand what the others want and why the want it, then you will be in a better position to outline your own objectives, since you could start thinking in terms of win/win.
By first listening you are also creating empathy with the other person or persons.
