Breaking out of your comfort zone can definitely feel overwhelming but it doesn't have to be. Take small steps. Do something different each day. Go to a different grocery store, drive a different route to the mall, eat at a new restaurant.
Have you been wanting to write a book but are afraid of rejection (that would be me)? I think the majority of writers will tell you they have been rejected, but if a book seems too much why not start with a short story or an ebook. Have you wanted to start practicing yoga, learn how to knit, take up swimming, or go back to college? Are you afraid to go to a class because the others may be better at it or more knowledgeable than you? They were beginners once too, and that is why they are called classes. They are there to help you.
What I have learned as I have grown older is that life is a lot shorter than we think it is. I know that I don't want to leave this world with a bunch of regrets. So today I will take a small step out of my comfort zone. I will start writing down ideas for an ebook.
What would you like to do that is out of your comfort zone and what is holding you back?
