First of all, it should be noted that taking risks is necessary for success. History is full of such examples in all fields, from science to war and from sport to literature. Those who simply continue tradition and never try anything new are doomed to repeat the past and typically content themselves with mediocrity. However, when people try new things, they may risk failure, but they also bring about the possibility of tremendous success. Looking at literature, for example, we can see great writers like James Joyce and William Burroughs, who completely redefined what a novel could be by breaking all the rules. They could easily have wasted their time and become mired in failure, but their risks paid off and they are today considered giants in their field.
Of course, that is not to suggest that taking a risk always results in success. Naturally, for every great success there are countless failures. To continue the idea of literature, one can only begin to imagine the number of writers who attempted to do something entirely new but failed because they were misunderstood. Taking risks in everyday life can be an even bigger problem because the consequences can be more severe. Young men often hurt themselves in foolish stunts because they took a risk to impress their peers. In such cases, it would clearly have been better not to take that risk at all.
In conclusion, whether it is better to take risks or not depends entirely upon the risk. In some scenarios, it is best to take a chance and see what happens because the potential outcome could be immensely rewarding, but in many cases it is rather pointless. Still, overall it is better to take some risks than avoid them altogether.
