Do one thing a day that scares you. Life is meant to be lived, so go out and live with your heart, soul and passion! It is better to be excited about the potential in your day vs. regret what could have been. Go get it.
Uncomfortable is only uncomfortable, until it becomes comfortable.
Get out of your comfort zone and explore your life and your passion. We don't grow by staying comfortable. Amazing things happen, doors open up, life begins, when you step outside what you know and make yourself open to the possibilities.
