Wanting to “make a difference” is perceived as a relatively trite ambition, but I would argue it’s not even an ambition. It’s a state of being. Existing is making a difference. You can’t help but make one by virtue of breathing. Simply because you consciously choose not to make something new doesn’t preclude the reality of ever-present novelty being made. Each moment is replete with new possibility, with difference. Life is perpetually making difference.
Now what kind of difference you will make? That’s different.
