What does out of the comfort zone mean to me

To me, it doesnt mean doing big thing which my mind can imagine by far, It just challenge myself a little bit, It just put some disciplines to my routine, it just some baby steps to get to my goal day by day.

Getting up a little bit early, making your bed, taking a walk in the morning and listening to yourself, praying, save an hour a day to read. I never write any article in the Linkedin but this is my very first and I considered it is stepping out of my comfort zone. Dont afraid of making mistake , just do it. All that little things gradually give you sense of winning , sense of success and building your self confidence. To me, it means stepping out of my comfort zone. What's yours?
