How to control your mouth, when dealing with a boss who's not psychologically healthy.

Hi.  I'm new to the commercial real estate world, NYC. I thought I made a good decision, in choosing my firm.... a little background, my "boss" (probably not the most accurate term) made over 1 mill, last year. From his own commissions.... I didn't know that until after I started working there. But I thought he would be a good person to learn from, things could be a good fit... I come from the fitness community. Proudly. My personal life consists of athletes/former athletes. I've read many books on psychological health, positive psychology, etc. And I have the requisite life experience to write my own book.... The person I work under feels entitled to speak disrespectfully, to me. Cut me off, talk over me, when I barely speak... and I come with wisdom. I come with value. I come with intelligence... also, is preventing me from working the hours that I need, when this is an independent contractor position... I feel like I might intimidate him...  I'm female, but I don't consider it, in any work environment. I hate identity politics. Strongly. With both race and gender, there should be no quotas or consideration for that. I'm all about meritocracy, strong work ethic, noble character. Thats what defines you, or should be considered for hiring.... so I'm not playing any female card here. I simply mention it, because if this owner/"boss," spoke to a  "real man," on the street, the way he has spoken to me... and/or enforced the (non-industry standard) restrictions that he has on me (specifically), simply acting in a bizarre dysfunctional manner.... it would result in violence. He would be floored. I don't view him as a protector. I don't view him as alpha (and yes, I still use that term), so I'm in a very sticky quagmire... I have a hard time constantly silencing myself... or confronting him calmly, and him spitting nonsensical unintelligent lies to my face, while me looking dead in the eye.... I'm a fighter by nature. I love that about myself. And strong men like that. Real leaders appreciate me.... I want to leave ASAP and I will!  I just don't want to leave money on the table. Or waste the work that I started. And I need the money! I need it.... I feel like I'm going to have to tolerate his dysfunction and injustices for a little bit, instead of cursing him out, telling him to go fuck himself, or calling him out vividly/publicly.... Do you guys/ladies have any strategies on how to deal with someone who you surpass in so many ways, yet feels entitled to disrespect you because they're simply good at sales in one niche market, which means very little in the grand scheme of things?   I've been fortunate enough to avoid these type of situations, thus far. And I'd like to continue to do so.  Thank you in advance for sharing your stories or advice.
