For uncovering limiting beliefs you can use this method.

Get a sheet of paper and write down what it is you are affirming. Like I have a New car... and pay attention to the first thought comes to mind. which might be something like yeah right that bomb isn't new it's more than 10 years old.
Repeat I have a new car.. write the next one. Where did you get the money to buy it? ...There's a limiting belief.. no money... gives you something else to take through the process.
