"...We might have never learned that having problems is the path to the growth and serenity we all seek... To acknowledge life as being filled with opportunity rather than problems is a tiny shift in perspective that gives us huge rewards." - Karen Casey.
It's in pain that our souls grow. We couldn't experience growth and serenity without it. When life gives us problems, we have a choice. We can get lost in the problem, bury ourselves in it, cover ourselves in it like a blanket and get comfortable in our discomfort. Or we can change our perspective, search for the opportunity, find the lesson, and bloom!
