Positive interpersonal relationships contribute to well-being.

Well-being is what is intrinsically good for a person, indicating how well their life is going. In the broadest sense, it is the balance of all positive and negative aspects. More narrowly, it refers only to positive degrees and contrasts with ill-being, which denotes negative ones. Researchers discuss types by how they are measured and to whom they belong, distinguishing subjective from objective well-being, and individual from community well-being.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
