She smiles; doesn't mean she's strong. She cries; doesn't mean she's weak. Sometimes smile is her loudest cry & tears are her last strength.
Don't say "Hi" when you're lonely. Don't say "Bye" when you're angry. A relationship shouldn't be started & ended by immaturity.
Apologizing doesn't always mean that you're wrong & the other person is right. It means you value your relationship more than your ego.
It's always better to be pissed by the truth than to be pleased by a lie. The truth hurts truly, but lie kills softly.
In the end you'll realize that those who judge you will never be as good as you, and those who hate you will never be as strong as you.
