What are you avoiding feeling or doing by staying in your comfort zone?
I once had a conversation with a man I met on a train about staying in one’s comfort zone. The man started the conversation on this topic by saying that he was not the kind of person who enjoyed staying in his comfort zone. He understood staying in one’s comfort zone as meaning somebody who hasn’t really travelled or hasn’t lived outside of their birth city or country, or simply somebody who is not really active. He himself had travelled extensively (travel was also part of his work) and he was leading a really busy life.
I had to point out at this time that keeping busy and constantly being in different environments did not mean that he wasn’t in his comfort zone.
