Never presume that cross-cultural communication will happen on your terms. Never presume that you are more enlightened, more knowledgeable, or more morally correct, than your client, or those who are the beneficiaries of the project with whom you are working. This is especially important in regard to teamwork. Do not assume that most people most of the time automatically are good team players. Indeed, high-flying achievers accustomed to ready success working and writing independently find their initial experience with team work slows them down.
Management requires more than intellectual discourse.
The challenge is to learn how to be effective, solve problems, and perform as a team player.
