The nature of business is that you have to be diplomatic – a lot.
Disagreements come up all the time. Working with parties who have conflicting agendas are all part in parcel.
Disagreement doesn’t mean you’re right and they’re wrong, or vice versa, it just means you disagree. Even if we can’t agree on these points, here are some we can, to build a relationship lets focus on these.
It’s often the lack of relationship which creates the friction, the differences can exist but a stronger relationship lessens the negative effects.
Never let your ego get in the way of getting to that relationsip. It is tough but means you can get to that bigger goal which makes it worth it. You’d be surprised of what you can accomplish when you do.
