A friend was in a meeting with a few colleagues when my latest book came up.
One person said, "After I finished it, I was all fired up, and I felt like quitting my job to go do something amazing."
The other one said, "That's funny. After I finished it, I was all fired up and I couldn't wait to come to work to do something amazing."
Fired up isn't something you can count on, but it's certainly possible to create a job, an opportunity and a series of inputs and feedback that makes it more likely that people get that way.
And fired up sometimes drives people to do amazing work with you, especially if you've built a job description and an organization that can take that energy and turn it into work that matters.
Give people (give yourself) projects that can take all the magic and energy and enthusiasm they want to give.
