I learned with my own personal experience, that we only know better our own culture, education, bias, and our own self, when we have lived at least few years in a different country and different culture (especially amongst locals). These (many years living in different countries and cultures) have expanded my horizon and my own identity, both professionally and especially personally. There is an emotional cost of "expatriating" oneself, but it is also truly a gift. There are many things that we cannot fully comprehend with only short visit, books or else, they have to be experienced over and over.

Ask questions! Don't assume you are talking about the same thing! Even in the same language, it is easy for you not to be on the same page.

You don't need to have 1000 goals, you just need a couple and to know exactly what those are, to articulate a clear road map out to get there and then doing your best is the right thing to do, knowing that we couldn't do better and that the current outcome is the profit of our hard work. Then, by creating a friendly and great environment you will never feel that you are working but just cooperating and having a good time with your mates.
