I've got 3 grown kids. 2 grandchildren. My life has mostly been better for it because it wasn't always about my choices (selfishness). That said, you have to get outside your bubble before you will know who you are, and too many people use children for that excuse without knowing that's what they have done. Who will you be if you begin caring for someone outside your self that you cannot stop caring for? All of your accomplishments seem to be formulaic. What if your child requires special medical care and the civilization you built around yourself is no longer available(disaster, divorce, employment, etc)?

You seem to have it all together, but whether or not you have a child, you may not get to keep the stability you have. Is your level of awareness different than the people you think are wishing you to have kids? Is your connection to them actually mutual engagement, or coincidental culture (people with kids tend to end up only associating with others who all got laid in the same year ;). Neighborhoods are built around economic commonalities these days, not familiar or local work: unless it's a college town bubble. Is childcare a choice for your future or theirs, and what is that future built on when it's not competitive consumerism (selfishness)? How will your child survive if taught something else?
