You don’t need a special job where you’re doing expert work and sophisticated things and groundbreaking experiments to feel great about the work you do.
The man in the quarry must cut stones to build the cathedral, but he doesn’t get to see the cathedral being built. So he must cut the stone while dreaming of the cathedral.
You don’t need a special job, you need a special approach to your job if you wish to extract meaning and fulfillment from the work you do.
What you input (your effort, focus, precision, and pride) will help you discover meaning in even the banalest work.
As the saying goes, the wooden wheel is not noble, but to be able to shape it is.
Whatever your craft, treat it as art and make it amazing. From building a hamburger, to filling out insurance forms, and from selling cars, to building developments, you can do your work well. In doing work well, you will find great joy.
