By widening the comfort zone, we touch the limits of the comfort line, and, touching this line, you feel uncomfortable. 

This band is called the learning zone. The learning zone is a temporary phase because the more the limits widen, the more we feel comfortable with the world we are creating for ourselves. 

Luvvie Ajayi says: ¨You can only grow if you are willing to feel awkward and uncomfortable when you try something new. "

To grow and develop your skills, try something new, and be brave of getting hurt. They call it life.
