I'm driven. When I'm working on an article, it can be pretty much 24/7. My intuition will wake me in the middle of sleep and I will come in and type something that I have just made a connection with. Sometimes I'm only getting by with about 4-5 hours of sleep a day to finish a compelling article.
My topics are interesting, riveting.
It is sometimes more fun to crank through hours, days, weeks, months of research to be able to pull together a compelling article that informs the public about very important technological break throughs, etc...
Who encourages me to do this?
Hmmmm... no one.
Writing can sometimes be a very thank-less type sport.
However, it just depends on your commitment to get the story out.
Some stories are worth losing sleep over... I've been lucky enough to hit on a few topics that are really great challenges and that I truly love exploring!
