“Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to an end requires courage.” - Ralph Waldo Emerson
Your Ego mind or that little voice in your head is your biggest critic. Your Inner knowing or Holy Spirit or Unconscious mind (whatever you want to call it) is your biggest fan.
The problem for many is they cannot “hear” their inner knowing but that little voice in our heads goes non-stop.
Start listening more to your biggest fan. God.
