It is a truth that 100% input from only you cannot breed success. There has to be a void filled by others both directly related or not. Even some research has shown that all humans are actually wired to complement one another. Now, a true friend is one who has demonstrated his true self and worth by his actions over a period of time and properly vetted by his own actions towards another person.

The way we relate not in isolation is what makes us social - as in society.
Good job here, @samminator
