Many people are afraid of being uncomfortable. They keep doing only what they have done in the past because it allows them to say within their comfort zone.
Other people are willing to stretch themselves to try new things and to grow.
It’s not that these other people are comfortable trying these new things but rather, they are comfortable being uncomfortable. The only way to get to this stage is to keep trying new things so you get more accustomed to doing things outside your comfort zone
You will most likely never get comfortable trying new things. However. You can get comfortable being uncomfortable trying new things. Keep stretching yourself, slowly leave your comfort zone and eventually you will get more comfortable in these uncomfortable situations.
Have a great day!
