I strongly believe in the importance of collaboration skills, but let’s also prepare ourselves for the fact that:

During our project management career, we will have to make numerous decisions that may harm someone’s interests.

During our project management career, we will also have to confront people sometimes.

During our project management career there will be people who will not like us.

During our project management career we cannot make everyone happy.

As Steve Jobs said, if you want to make everyone happy, don’t be a leader, sell ice cream!
