Doing What You Love or Doing Something With Passion

I just finished a great conversation with a dear friend about doing something that stirs your passion. Here are some thought about how passion creates value.

I think that doing what is close to our true values is a key to creating value. Passion is a spark. A fire within, and when we are doing what we truly love, we do it with passion. Doing it with passion means that we can do it 24/7 without being bothered one bit.

When we are passionate, we have endurance. Doing what needs to be done becomes a non-issue! I would be curious to know how many people are working at jobs that they hate? I'm pretty sure that there even could be a correlation between passion and longevity... unless you have a passion for dare-devil activities!

Does anyone have any statistics on this?

Does anyone have stories, either your own or someone else's, of someone doing something with passion?
