Say whatever you want
Give zero fudges
Establish your own persona and don't let anyone get you to stray from it. Understand and respect your own values.
Don't be afraid to walk away.
Whoever cares less has more power.
Love isn't something that just happens. It is an earned feeling.
Someone who doesn't add value to your life (be it the same sex as a friend or opposite sex as a mate) isn't worth a whole lot of your time. Someone who takes value away from your life doesn't even deserve a place in your contacts.
