Her tips to become more culturally competent are:
Take the time to do (some) research. So when you come to a new destination or meet new people you know something about that culture. Not all, but something.
Be open to new experiences. Realize that new cultures can enrich you.
If you can, Travel. Even if it is only within your own country. Set out to make a friend where you go.
