"This can give you better insight to the wider world and making you a more rounded person." It's hard to translate it perfectly. Korean phrasing will change depending on what "this" means. Is it some fact, a work or an experience, for example? Anyway, here's a couple of possibilities. 1. 이것이 저 넓은 세상에 대한 더 깊은 통찰과 원숙한 자아를 가져다 줄 거예요. (using big words - very formal) 2. 이럼으로써 저 넓은 세상을 더 깊이 알게 되고 생각도 속 깊어질 거예요. (simplified - how we would commonly say it)
