In a sense, love is sacrifice. Popularity is not so important as respect. If you strive too hard to have people like you, they probably won't. But if you strive to win their respect, then they will both like and respect you. If you have self-respect, you will win the respect of others.
Nobody respects a liar, a gossip, a cynic, or a whiner.
Never make promises lightly, but if you make them, you must keep your word. If you read a lot, and discerningly, people come to value your judgment. Sometimes it requires more wisdom to take good advice than to give it. Character is what you have left over if you ever go broke. The real riches in life are family, friends, health, and a good conscience.
