Everything happens to you and for you. Milk it.
With the recent neck injury, my body went into a downward spiral of inflammation. Immune response slowed down. I picked up a cold. Day by day I was getting stiffer and weaker. Came to a point that I couldn't go through the first 15 minutes of my usual workout. I started reacting defensively to people, tried to control the kids.
Once again my body has left me no other choice but to figure this out. So, I started with neck stretches and hip openers. Both were too tight to stretch out. I took a deep breath and got the dowel from under the couch. If you are not familiar with dowelling (self massage, here is the link http://www.yogaworlds.net/10528/), it's similar to foam rolling, but done with a rounded piece of wood, hence making it more precise, going through deeper tissues, and waaaay more painful. 3 hours and numerous moans and thoughts of suicide later, I was knots free. All of me. It felt almost unnatural. I slept like a baby for the first time in a month.
The next day I went to the gym. Weights felt like feather, routine barelly broke my sweat. Why was I avoiding the stick for so long? Well, I did what I did. Now that it's done, what can I learn from it?
You gain courage and strength by every experience that makes you stop and look fear in the face.
If adversity would not present itself, I would not get the courage to take the steps to better a bearable.
