It's strange to remember how we used to think, as if everything were available to us, as if there were no contingencies, no boundaries; as if we were free to shape and reshape forever the ever-expanding perimeters of our lives. I was like that too, I did that too.
The quote reflects on a previous mindset where possibilities seemed limitless, illustrating a sense of freedom and the ability to mold one's life without constraints. It acknowledges a past state of mind that was characterized by optimism and flexibility, suggesting a time when the individual felt empowered to explore and redefine their boundaries.
However, this nostalgia is contrasted with a recognition of current realities that impose limits and contingencies. The speaker expresses a sense of loss about that earlier perspective, hinting at how life's complexities and restrictions can alter one's outlook over time, marking a poignant change in personal freedom and potential.
