In this session, she talked about her ambition. She wants to continue her activity as long as possible. Her desire is to sing her favorite songs at higher intervals when she reaches 80 years old.
Surprisingly, to realize her dream, she practices singing for 3 hours every morning.
As you know, it is extremely difficult to do something continuously. Spending 3 hours to an exercise is all the more tough task. For me it is even too hard to write this blog every day.
Why does such a talented person make efforts?
There are some studies to investigate the relationship between talent and effort. One research suggests that being able to make continuous efforts is a kind of talents. I think that this hypothesis meet our experiences.

Other research indicates that most successors made efforts, but the effect of their endeavor depends on the talent, as I remember. Unfortunately, I forgot the detailed content of the original paper. Considering the results of studies, the relationship between talent and effort is more complex than we imagine.
Finally, I believe this: it often occurs that an effort is not rewarded, but there is no effort not to be rewarded. Simply, it is a matter of the amount of effort, or by chance.
