In my point of view, I "Exist" when somebody can see me, know me, feel me, and appreciate everything I do for my small world. It will not happen if I do nothing for them. Thus, people know somebody else because of her/his fame, hardwork, kindness, and etc.
In addition, I surely believe that not all of people like to take a risk in her/his life so that he/she choose to do the same thing almost along their lifespan. However, there are many people too who love to find something new and meet new challenge, an adventurer or a risk taker. They like to think "out of the box", the creative one. However, this phenomenon depends on how we see the world and what our heart needs from the world. Being stuck on our normal activities or being a risk taker to reach success, that's a choice in life.
