Exactly! It's the same problem I see: people always want validation from others. It makes me sad thinking how they end up neglecting themselves because of their desire to please everyone. While this might not be entirely bad in itself, too much of it is quite destructive.
But yes, this definitely has to be spread. I always try to talk to my friends about this and make them realize their self-worth... I can talk about it all they want but in the end, it's really up to them on what they're going to do about it. :)
