Comfort zones are unique things. They are what you are used to , they are safe. But if you want to change and become better you have to step out of it. If you are like me and like control it’s hard. You don’t know what is out there and how to deal with it. The latest “outside my comfort zone” thing I’ve done is meet with a girl about starting a young adult group at church and learning how to drive. 
It’s hard to do but sometimes you have procrastinated long enough where you just have to do it. That’s driving for me. It’s been a learning experience. 
Stepping out of your comfort zone is a neccesary step to have the best life possible. You can’t be scared of everything.
