I know more about myself than I care to. For example, I know I have an intense personality. This has been a mantra spoken around me since I was a child. I am quite serious about getting the job done and done right. "All work and no play," is something that might end up on my epitaph.
I would prefer my epitaph to say, "she brought a lightness and support to people, showing them the best they could be and become." ***Note I still try to break the limits, but I also bring lightness and support to the effort.
Yoga has changed the circumstances of my life, it has only offered me the power to notice why and when I step into that intensity; the power to choose "all work" or "lightness & support," or not. It is the choice that will change the circumstances.
If you want to know what makes you tick. If you want to practice a happy life, then a deeper study is for you.
