Never beg someone for their attention. When you beg people they feel powerful so they take control of your feelings. The right people will give you their attention and love freely. Always always remember that!
Don't chase someone who won't chase after you. Don't give to someone who doesn't appreciate you. NEVER push a loyal person to the point they no longer care. It takes work to get a person to that point and once there . It's hard to repair the damage
