You can’t choose to see a failure or success without choosing to mark a point in time as some kind of judgment or finish line - even though time always keeps moving.
In other words, you might be a failure today but not tomorrow. Or that might look like a success today but not in 100 million years.
In other words, failure and success are both incredibly arbitrary markers and maybe the most subjective and opinionated words in our language - and some of the most fluid ideas in our language as well - and yet we tend to base so much of life, of perception, of decision making, of relationships, of self-confidence, of everything… off of both of them.
We have to try not to.
