" What do you do with this inner trash talk? Similar to athletes who deal with trash talk, you have to learn to focus on the task at hand, not the trash talk. Think about it. Do you ever see a visiting football player try to hush the home team’s crowd? Of course not—it’s not a productive use of energy. In the same way, trying to tell your inner voices to stop talking trash will only increase their volume.
Once you allow yourself to confront this trash talk head-on, you may start to see ways to move past it. It can be hard to be honest with yourself, but the Think part of engaging your core is key here. Ask yourself: Where do these thoughts and beliefs come from? How do they serve me? What would it look like to move past them?
This is the time to stop accepting all of your trash-talking thoughts as truth and discover new ways to move forward. "
