* My sister is very confident in herself (looks wise, socially, in her career - rightly so), but she's not emotionally mature: she doesn't consider others' feelings, is dismissive of negative feedback or criticism as she doesn't believe it applies, struggles to maintain relationships because she doesn't like/think she should have to compromise/have discussions etc. Those are all things I'd class as a sign of emotional maturity - being able to compromise, have difficult conversations without shutting them down or not hearing the other person's point, being willing to accept and understand criticism.*
You are basically viewing an alpha personality from an omega perspective. My own sister describes me like you have done - but I am happy and successful precisely because I rarely compromise on what I want or my goals. I don’t have long protracted discussions to find out what went wrong or how I can meet someone in the middle of every argument. When I truly believe in something I focus my energies on influencing the other person to my way of thinking.
Different way of thinking / problem solving.
That's an interesting way of looking at it. I'm sure the world needs people like that as much as it needs people who are willing to get into the murkiness of balancing emotional needs and giving a little.
But I think there needs to be a balance.
Compromise is not weakness or lack of ambition - sometimes it's necessary or kind or both.
In a slightly-edited-for-anonymity version of my sister's example, her fiance wanted to move from City A to City B (about 3 hours' move, closer to all families involved) for a huge promotion in his fairly niche line of work. Sister is self-employed, clients internationally, can work anywhere. She said no, she wanted City A (fair enough, of course) and that was that. She refused to entertain a discussion, a compromise, anything. Just 'no', because why should she compromise and not be true to what she wanted? She might have got her goal of staying in the city she wanted by refusing to compromise, but it was the end of their relationship and she was heartbroken. Couldn't possibly understand why he was so unreasonable as to move anyway and end things - she lacked the emotional maturity or insight to realise that her refusal to even discuss the matter made the man she wanted to marry feel as though his opinion was unimportant.
To me, emotional maturity in the event that she was absolutely unwilling to move would have been to explain her reasons to him, understand if he wasn't willing to change his mind either, and accept that that might mean the end of their relationship.
But she couldn't do that.
So I don't think - in her case, anyway - it's being 'alpha' and putting her own goals first, because it didn't make her happy. What would have made her happy is getting her fiance to agree to her version of events, and she couldn't achieve that because she wasn't even willing to discuss it or give him a reason, she just said "This is what I want, take it or leave it". That's not emotional maturity, that's stubbornness and failure to consider the consequences of her actions.
