One more thing just came to mind. The biggest problem that you may encounter is dealing with officials in some countries. Some cultures don't deal well with women as people in authority.
I am a very large man and I also had problems with some of the people that came aboard from other countries. I found it quite advantageous to let them push me around a little bit. I would usually have some piece of paper-work out of order and let them tell me to fix it. It helps to let them be "In control". I would visibly submit to their authority, to let them know that I know how important they are (because they are). As long as you show them respect, you can be business like and not apperar to be vulnerable. I would also suggest being polite and business like but not
too friendly.
