The Comfort Zone : Is the location of skills and abilities we've acquired, while the comfort zone is by definition the most "comfortable" , we can't make progress or build skills, it consists of the skills we already are able to do easily.
The Learning Zone : The skills and activities that are just out of reach are in the learning zone they are neither too far away for us to panic or too close for it be that easy. Well here you have the ability to take your time and actually learn.
Hope this helps!
