“The primary cause of unhappiness is never the situation, but your thoughts about it.”
“Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
~ Eckhart Tolle
This rings very true for me. If I stop the thoughts after the initial feeling and refocus I am okay. It is only when I allow myself to think about a situation and how upset I am that it has not gone the way I needed/wanted it to go that I become anxious, depressed or down. By working with thoughts we can shift our mood.
I like the second quote as it helps to shift thoughts. I honestly believe that situations we find ourselves in always contain something for us to learn, shift or grow from. I start there and then move forward. At least in my best moments. ; )
