Fear of not making money

There are a few business ventures I’m really interested in, but when I think about pursuing them, these thoughts come up “I won’t be able to make money”, “I’m going to fail at making money because I’ve never done it before”, “I’m going to put in so much effort and not make that much money”, “What if I end up not making any money at all, so I end up wasting so much time”. How should I tackle these unintentional models?
It’s strange because, at the same time, I do believe “I’m capable of creating any life I want”. Does this mean I actually don’t believe that empowering thought?
