It seems there are four ways you can be passionate about your work.
The Work: The actual activities and tasks (research, writing, supervising, building, designing) that take up a work day.
The Results: The end product (a valuable report, a book, smooth-running company, a building, a clothing line) of all the work you put in.
Customer Benefits: The benefits your customer receives (confidence, entertainment, stress reduction, a home, pleasure) as a result of the product of your work.
Your Benefits: The benefits you receive (physical, financial, emotional, psychological) as a result of your work.
And if you can get all four…
Let me know what you think. Did I miss anything?
