I might be able to help out here a bit. I am consistently scored as much more I than E. I work from home about 60-70% of my time and I do work travel the remainder. My work is very much in the sales/commercial realm, so it's all about meeting people and forming relationships. I am not good at small talk at all and I'm terrible at starting conversations with new people. It's so much that I'm shy, but would definitely prefer to be alone and often times don't have much to say.

Some of my specific tips:
- when talking to people, ask questions. People love to talk about themselves (especially extroverts!) and they like people who allow them to do so. One tip I learned from Barbara Walters' autobiography: ask people about their first job. People love to reminisce and it brings up all sorts of tangential conversations.

- when traveling, build some time for yourself. Rather than zipping in and out of a city for a meeting, if your schedule allows it, spend an extra night or block an afternoon to check out a local sight, museum, restaurant on your own. You may not be in the comforts of home but at least you get a little perk and the all-important alone time.

Happy to share more...
