Maybe the people you think are lucky feel they're unlucky, and that
you're the lucky one. Your outlook determines that.
Having said that, I know a guy who's born into a rich family, has a top-dollar job, and is tall and handsome and seems to have girls all over him, and he's only 23. Is he lucky? Yeah, I believe he is.
I have depression, sexual anxiety, low confidence, and am not tall and handsome. Am I lucky? In a sense, yes. Why? I was born in a first-world country to parents that aren't abusive and a brother who likes me. I think those odds speak for itself.
