Yes. Sometimes you must step out of your comfort zone in order to grow.
a person sometimes needs to separate himself from family and friends and go to new places in order to change?
I believe this concept can be split in two varied definitions.
1.Sometimes a little bit distance is good for any individuals. When an image be too close you can not see the details, but a little bit distance can help you to see the whole perspective and see the underlying routes and actions during the effort. It can involve with a high positive impact.
2.Yes! One way or another we have to gain our distance. We can not always stick with our small secured world sheltered by family. An undeniable fact is family can't and won't be there forever, we need to learn how to survive and cover our life. One day finally we need to get over the path in our journey on our own which helps us to gain experience, knowledge and skills. The challenge of taking the journey on your own helps you to grow, to observe and to be built by a better structure.
Some people do need to do that. It isn't always a guarantee, but sometimes it helps to get a little distance, and a fresh prospective.
