I too had a difficult childhood and overcame some moderate difficulties. Then I proceeded to waste my adult youth (20s and most of my 30s) in a multi decade pit of depression and withdrawal from the world. So let's not forget survivorship bias.
Tragic.
FWIW, in my opinion (and in the opinion of evolution and biology), raising children is the purpose to life. By having children, we give another human the ability to experience life. And, for most of us, they are the only lasting mark we will leave on existence.
Can you give me an example of what you would consider a “real goal”?
