Wish I could learn this one! It is a good way to find out who your friends really all and will give you some space. Those summer time friends who think it is all about them get their pantyhose in a knot if they aren't the star in your life every moment.
If you want 2017 to be your year; don't sit on the couch & wait for it. Go out. Make a change. Smile more. Be excited. Do new things. Throw away what you've been cluttering. Unfollow negative people on social media. Go to bed early. Wake up early. Be fierce. Don't gossip. Show more gratitude. Do things that challenge you. Be brave.
