I am strong because I am weak. I am beautiful because I know my flaws. I am a Lover because I am a fighter. I am fearless because I have been afraid. I am wise because I have been foolish. I can laugh because I've known sadness.
Jealousy comes from counting others' blessings instead of our own. So very true, don't let your life pass by while you worry about someone else, count your blessings, be grateful, be happy for others (even though it can be hard).
