I've just seen my dad talk to one of his clients and asking them about themselves and how they're doing and stuff, that's obviously a marketing tactic and he does it to all his clients. How do I become good at that ?

I'm some kind of sociopath, but I genuinly don't care about anyone's life or how they're doing. Not most people anyway. How do I make myself care ? it's not just about marketing, even when talking to girls you're supposed to get her talking about herself, but how can I do that when most of the time when she's talking about herself I just wanna leave ?

I've lost so many girls because of me just not talking to them anymore. Last time it happened is yesterday, I've known this girl for more than 7 years and have been always a pussy to make a move. Friendzoned obviously. I used to talk and text her all the time, now I leave her seen all the time. She double texts and gets pretty mad, but I just say that I'm busy or don't feel like talking. I really don't, I don't want to talk, but if I don't, there's no hope for me in relationships.
