Fear is a human necessity, it makes us cautious in cases where we need to be cautious. Our ancient instinct is to feel safe and to stay away from any danger. Even most of us still choose to play safe "games", avoid taking risks, or choose to ignore risks when faced with choices in life. Today, stepping out of the comfort zone is "daring to commit and daring to change". You can change slowly so that you get used to the new version of yourself, with the changes around you.
