The worst feeling is thinking you should have it all together by now or be somewhere else. It is all too easy to become negative about your life if it isn't where you thought you'd be. Stop, breathe, listen. You are living. That is life enough.
"Be soft. Do not let the world make you hard. Do not let pain make you hate. Do not let the bitterness steal your sweetness. Take pride that even though the rest of the world may disagree, you still believe it to be a beautiful place." - Kirt Vonnegut
