Establishing boundaries is a vital part of healing. Through developing awareness of where you had poor boundaries in the past and then finding ways to strengthen them, you will start to notice a difference in how you cope with problems in the future. I used to keep quiet out of "politeness." Now when I'm in a situation that is making me uncomfortable I ask myself this question: "What would I gain from speaking up for myself and what would I lose?" Setting new boundaries where there weren't boundaries before is challenging and takes practice—just remember you can say no. 

If life were predictable or "fair," it wouldn't be a great mystery. What do you do when things don't work out? What do you do when you have to let go and move on? You find acceptance. As Cheryl Strayed puts it, "Acceptance is a small, quiet room." What does she mean by that? I think she means there is loneliness in that room...but also peace. 

To breathe, set your intentions, and dream with care is some of the best advice I've ever heard. If that's all you do today it is enough...and tomorrow is a brand new day.
