Money mindset from parents

I think the most annual income my parents have individually earned is $250k. They grew up with a scarcity money mindset because of their childhood. I want to create more abundance for my family and myself and my current income goal is $1M. I recently uncovered these deep subconscious thoughts that are really bothering me because I don’t actively think them and they’re so negative! “That won’t be possible for you because no one around you has done it, so what makes you think you could do it”, “Who do you think you are, trying to believe that’ you could earn that much money”, “You’re not outgoing enough, charismatic enough, or have an interesting enough personality to be someone who can make that money”, “Only rich people can get rich”, etc. So these are complete bummers and I hate that, deep down, I think this way. There’s a lot of self-loathing and self-doubt that’s there, even though they don’t’ show up every day. How do I do this thought work?
