While I think being loved and being happy are important aspects of life, I don't think they are how I would define "success". In my mind, to be successful requires having certain core values and intentionally working toward accomplishing something.
To me, success is making deliberate choices that cause your life to reflect what is most important to you.
Because we all have different values, success is different for each person and our definition of success will (hopefully) change over the course of your life as you grow or as you're exposed to different environments or cultural expectations. If someone values prestige and expensive goods, then their idea of success is going to be completely different than someone who values human connection and empathy. Someone who believes generosity to be extremely important may define their success by how much they are able to give, but someone who values creativity and originality may define success by what artistic legacy they leave behind.
No judgement on anyone, but no teen pregnancy and no daughters on a pole

...
you see, everyone’s “success” is subjective.
It certainly is subjective. Throughout my life, I think people have tended to describe me as successful
despite being a teen mom but I believe that most of my successes and positive attributes are actually
because of my situation not in spite of it. For both my spouse and I, our education, our marriage, our financial stability, our parenting, our empathy and ability to relate to different types of people, etc. are all directly influenced by the fact that I had a baby in high school. It was not an embarrassing "mistake" that had to be overcome; it was a motivating presence that impacted who we are as people and all of the life choices that followed.
I recognize that your post was made in a joking way, but the sentiment is true for a larger segment of the population than I think most people realize. Having two now adult daughters myself, it's absolutely bizarre to me how many people define their own success as a parent by their child's sexuality.
