I recently had a birthday and as such, I have been thinking about time. Specifically, I have been exploring our societal understanding of time and how this understanding intersects with our judgments and assessments both of ourselves and others. I have lost count of how often I have heard someone say, "He's doing pretty well for his age." Our assessment of our success is often greatly determined by our age. We diagnose developmental delays and disorders using 'milestone' measures. Often our understanding of self and self-esteem is largely based on how we compare to our peers. I wonder how shifting our understanding of time and milestones would shift our understanding of self?
