I received comments from a friend recently who told me - Stop saying things in your podcast like - maybe you don't agree, maybe don't like this, don't laugh, don't say or act in a way that may discount all the positive things you do. You already sound humble, relatable and you don't come across cocky or condescending. After all, If they don't like your message and don't agree, they would not be listening.
When using self-deprecating talk be sure you are not minimizing your strengths. It is ok to connect through your human side, but don't minimize your talents and abilities.
You don't need to make yourself small to encourage others to enlarge.
