This is a tangent, but perhaps similar to what you are saying.
Dare to stand out. Even if it’s unpopular and immediately pushes away 90% of people. Your goal when dating is not to make everyone like you. It’s to find one person that loves you.
And if you're playing a part to get a result; you'll have to keep playing that part. It can work for a job, but it's a shaky basis for a long-term relationship.
I'm a sadistic fuck that's been made to have the caring range of a rock due to childhood abuse
I'm fine being that way, it's just not conductive to maintaining relationships. Been there, done the whole 'be yourself bollocks' - the results were shit. Pretending to care far more than I do, and constantly suppressing the sardonic and vindictive tendencies has been far more pleasant
'just tweak core aspects of your personality' is exactly the opposite of being yourself
(Don’t ask me how I know)
