GiYaaN Ki DuNiYa

Knowledge is, roughly, useful information. It is information that's adapted to a purpose. It is good explanations, and it is solutions to problems people had.

Knowledge shouldn't be expected to be perfect. Knowledge is the key to success. Without knowledge, we could not accomplish much in life. The more knowledgable you are in a particular field, the more money you are worth to a particular company, hence you'll be paid more. A partial solution is still knowledge, even if it contains some mistakes, and can be improved on in the future.
