"Vanity is so secure in the heart of man that everyone wants to be admired: even I who
write this, and you who read this."
– Blaise Pascal
Everyone seeks affirmation of their worth. Keep an eye on how you go about it and see if you avoid being conniving.
I don't think anyone can really be completely self-sufficient – even the most confident people I know get unsure and feel restored by praise or imitation or attraction – so accept your need for some admiration. Then go about getting it as honestly as you can.
I probably hardly need say that this is particularly important when it comes to relationships, eh? Don't make you partner do a little dance for your love; give freely and accept graciously that which is genuine and caring.
