We recommend focusing your energy on reinforcing the positive beliefs you have been programming in by looking for evidence of the new positive beliefs in your reality, taking action on your new positive beliefs, and concentrating on embodying the positive beliefs you are programming in.
The one exception to this is if you speak multiple languages fluently. See more on this here. In this case, we encourage you to go over the limiting beliefs in all the languages you speak fluently/natively.
