How to get rid of my big ego :(

Could someone help me? I don’t normally rant online or ask for help but I think I really need it atm. I think I am too prideful and have a big ego. I hate myself for a lot of things, this being one of them. I don’t know how to control it or be humble. My excessive pride really ruins many things for me and it’s not dying. Because of my pride, I think I am very judgy. Because of my pride, I tend to ramble on about myself. Because of my pride, I think I defend myself too much and never really take faults. Because of my pride I tend to underestimate people and always think I am right. I am trying to work on not being judgy, taking faults, admit I can be wrong, admit I don’t know many things, and try not to underestimate people but it’s become so much of a habit it’s hard to get rid of. If someone knows what I can do to get rid of this and be a better person, please do tell me. Thank you.
