How? Truly, I'd like to know why it's necessary. I've never been in a situation where it is, and I've still achieved promotions at past jobs.

Who would you need to impress? Work? Not necessary whatsoever. Lover? Technically, it's not necessary. You can be loved without being impressive. I'm struggling to understand where at all impressing somebody would be important.

You'll understand eventually. None of those truly matter, and mental growth is realising that.
