Well first of all, happy birthday! May this year bring you much joy and peace. I feel this poem so much, with my own birthday coming up in a few months, it's usually a bittersweet time. This is such a reflective piece, and I seriously relate to the comparing, especially with those around our age who have those big milestones and we feel inadequate in some way. I am happy, though, that you seem to be content or at least grateful for all you have accomplished thus far as suggested in the last few lines. Because how often do we go back and think about what we could have done more of or what could have been? And we'll never find relief that way. We'll never make it to a point where we're at ease with ourselves. You wrote a lot of truths in this that I think many people can take something from. That fear of life not going as planned, then focusing on it where it ultimately brings us down, can be daunting... but we can overcome it and try to just "be" in the present.
