Curiosity is a priceless yet costly character that one can achieve by abolishing many senseless predefined characters. It is a fundamental gift that everyone should receive, and better to accept it now, not any old. In history, it is beautifully depicted how impeccable a person can be with his curiosity and ability to find what can't be found.

You, at some point, will or already have realized that being idle is also a curiosity. Not virtuous, yet you are finding, not consciously, the results for being nothing. That, however, never promotes you to do "nothing." 

Curiosity drives more than it stops. 

My cabinet couldn't afford fancy and expensive collections but was a pure collection of paintings, some books I considered worthy, some notebooks, and a book on 'F=ma.' I am sure the last piece in my anachronistic chronology was pure gold (Hawking's small books), at least when I was 8 or 9. My cabinet also had a book on Geometry; I still have that,

But what constitutes a perfect cabinet of curiosity? I don't know, but I guess in ancient times, or perhaps medieval, when kings and connoisseurs were making their cabinets, they included many precious things in them. We can't imagine even finding some of them now as they were exquisite in that period. I recommend you read some articles and books on it. Kings of those times were likely to build one hall or building to showcase what they had. Now, what they had is a different matter, but what to emphasize is that we have lost its culture. Though people, often academians, build a library that contains only books. I know some people who like to collect paintings, and their house is just paintings by artists like Van Gogh. I haven't seen any theatre of curiosity, and I hope to see it soon.

Curiosity is different for different persons. It pushes us to know what we can't, and I assume many have this definition in their books. However, some believe it to be a pause for us to stop searching. Curiosity doesn't mean you have to find what is to be found; you have to find what you want to find, which is the classic definition. Some doubt, in philosophy, how much curiosity is good. I have no idea; curiosity is not an entity of quantity, so how can we put an upper or lower bound on it? Curiosity is nothing if tied to the environment, and hence environment is the key to the 'subject' for defining what lies beyond curiosity.

An important thing to note is that there is a sentence in literature, "curiosity killed the cat," so we better not pry much and call it curiosity. Some works can be done without curiosity, and some need them badly. Science falls in the latter category.
