Having Fibromyalgia, as I do, my threshold for pain and patience have changed. Over time my skin has become extremely sensitive to cold, so much so that cold water feels like hot oil when it touches my skin. On the flip side, having chronic pain means that pain becomes an everyday experience, therefore it becomes kind of normal, so the amount pain that I can tolerate and carry on with my daily activities has increased. But when I am fatigued and in pain my level of patience can drop drastically.
This got me thinking about the experiences we have and the level of tolerance we have for different things. Experiences that cause anxiety will greatly reduce what we can tolerate, but experiences that cause self-confidence or contentment will increase what we can tolerate.
Being someone who regularly meditates will certainly help increase our tolerance levels. It is worth having a look at what your day to day experience is and where your tolerance is with different things. Then look at how you can improve these through self-reflection, meditation or something like Cognitive Behavioural Therapy. This is on the path to self mastery.
