Taking risk does not always provide good experiences. Even then people take risks and it is very difficult to achieve something new without taking risks in both professional and personal lives. I believe taking calculative risk can make our life much easier and innovative.
we cannot achieve anything new without taking risks. When we are trying to do something new or creative we should take risks. No innovation came without the taking risks. For example, without taking risk it was impossible to conquer Mount Everest or Moon. Discovering India by a sailor was a big risky task.
On the other side, taking risk can cost a lot even life too. There are so many examples around us that people lost their valuable time, money, effort by taking risks. But what is important that, these failures make new ways to new developments. Sometimes we get benefits from these failures or sometime our successors get advantages from learnings of failures.
However, when people take calculative risks, there is much more possibilities to do something new in their personal or professional life. For example, if a person wishes to build a computer program without having zero knowledge about computer science, most of the time he or she will be failed, But if he or she make a plan to study about computer science first, then makes the computer program will carry much more possibilities of success. If a person cannot swim, he will not able to cross the river without help of other or any object.
Finally, something new and innovative comes with lots of risk. It has both positive and negative sides though. My opinion is to take risks in a calculative way which may gain much more positive results.
