The concept of comfort zones is a very simple one. It refers to the boundary lines that we draw around our personal space, and the limits we set for ourselves. 

We set boundaries to ensure that we don't go beyond those lines, and that we can make ourselves comfortable. 

We as humans lack motivation everytime and we want everything to happen automatically without hard work. 

But it is not possible, while working for success you need to work hard and that's the point where your comfort zone collides with your dreams.

Identifying your comfort zone is a crucial step to staying out of trouble. A person who knows their comfort zone is likely to stay out of trouble and stay in control of their life. If you don't know your comfort zone, it can be difficult to identify it, and it can be easy to stray from it.
