Is there any philosopher more cogent than Bill Watterson, the creator of Calvin and Hobbes? This is the thing about gardening; it's a high value activity. When you focus more on the quality of the interaction, the quality of what is done, and when you do that the newest model car will seem quite unimportant. Do you value what you do in life, or is it just all about the celery, oh, salary? Sorry, got caught up in the gardening thing there.
