“The thing I remember best about successful people I’ve met all through the years is their obvious delight in what they’re doing… and it seems to have very little to do with worldly success. They just love what they’re doing, and they love it in front of others.”
Quote from Fred Rogers
American Heritage Dictionary
1. The achievement of something desired, planned, or attempted: attributed their success in business to hard work.
You can totally tell the people who are in the job because they love it and those who are in it for the money or the prestige. If you hate what you do, no amount of money or acclaim will ever satisfy, but if you love what you do, they become just an extra, appreciated, but unneccesary, joy.
