What makes creative people tingle are interesting problems, the chance to impress their friends, and caffeine.



Don't forget that Rupert Murdoch has always regarded the Op Ed pages of 'The Wall Street Journal' - as he's said to me - as a cup of strong caffeine that gets you going in the morning and tells you what to think.

Caffeine is hard on an empty system, so I try not to do it unless it's to get my heart rate up. If you drink caffeine 15 minutes before the workout, it can make it more effective. So I'll do tea or coffee after breakfast.

Some great soups are filling and warm. So, at the four o'clock hour, when people are craving caffeine and a cookie, soup is a really great option because it fills you up and feels like a meal, so it can keep you going until dinner, but it's not hugely caloric.

Everyone has a different opinion when it comes to caffeine during pregnancy. I work full time, and with the extreme exhaustion pregnancy brings, I need a little boost a couple of times a day. On days when I can't stomach coffee, green tea has also proven to be very helpful and soothing.

Espresso, made by steam expressing finely ground coffee, is rich in flavor and aroma and chlorogenic acids, but not very concentrated at all in caffeine.
