Frankly, curiosity is a prerequisite to your success because it signals a hungry mind. 

If you're inquisitive, you're open to new experiences. 

You can generate more original ideas and produce novel solutions to complex problems.

It makes your mind pro-active.

Curious people always ask questions and search for answers. Their minds are always hyper-active. 

Since the mind is like a muscle which becomes stronger through continual and consistent exercise, the mental exercise caused by curiosity makes your mind more robust.
