I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
“Being yourself” can be somewhat complex, though.
Our concept of self is more fluid than most people realise, and we will often be very different in different social groups. We might not even notice this until those social groups collide. Each version of yourself is no more or less “you” than any other.
Thanks for the quality comment. It really is difficult to define since the sense of self is just a concept to begin with.
By being yourself, I would take that to mean being true to your intentions, interests, and general demeanor in the moment. All those can change with time.
Avoiding things like pretending to be interested in sports, pretending to hate comics, pretending to be a “player”, pretending to be overly macho, hiding politics, etc are all things that I have seen people do. If your interests change that’s normal but I wouldn’t recommend feigning things that are untrue for you in the moment.
I think aspiring for self improvement would still count as being true to yourself if you genuinely want to improve.
