Beliefs about Money

I have a recurring thought about money that I know is not helping me move forward with what I want. I made 175k this year in my regular career and I want to start a coaching business and not take a hit to my annual income. I continue to keep thinking I cant make 175 in 2022 from coaching. This is obviously causing a negative model where I feel unmotivated, defeated and is leading me to fail before I even start. The only outcome I see with this current model is that I clearly will not make 175 in 2022 coaching. So I get that but am having trouble not believing that its true. Any tips on how to change your mindset from an unintentional model that is not serving you but you are having trouble believing something else?
