Yes, Yes, YES!

Found via Matt G, Letters of Note has posted a letter by Ayn Rand that nails it perfectly:

Any person who wants to live for others — for one sweetheart or for the whole of mankind — is a selfless nonentity. An independent "I" is a person who exists for his own sake. Such a person does not make any vicious pretense of self-sacrifice and does not demand it from the person he loves. Which is the only way to be in love and the only form of a self-respecting relationship between two people.

Again, I say YES.
