If you want to grow, you must step out of your comfort zone. Comfort zones do a lot to soothe a wounded ego or to bolster your confidence but to experience real growth, you need to step into a new realm and try something brand new.
Yup, it’s scary for sure, but what if it works? You’ll be even more confident to try new things going forward. What if it fails? You’ll learn some lessons that you won’t repeat in the future. It’s all good and will all benefit your life.
