I've been doing some research and came across this quote. I believe it is extremely important, as many people misunderstand, misuse, and misapply the concepts of individualism and selfishness.

"Do not make the mistake of the ignorant who think that an individualist is a man who says: “I’ll do as I please at everybody else’s expense.” An individualist is a man who recognizes the inalienable individual rights of man—his own and those of others.

An individualist is a man who says: “I will not run anyone’s life—nor let anyone run mine. I will not rule nor be ruled. I will not be a master nor a slave. I will not sacrifice myself to anyone—nor sacrifice anyone to myself.”
-Ayn Rand
