I recently came across this quote in the Bio of a yoga instructor that I'm a fan of (Jay Holby at 8 Limbs Yoga)
"The main block to transformation is the thought that we shouldn't be where we are, that we should already be further along in our growth than we perceive ourselves to be." - Swami Kripalu (Source)
I really like this insight. I can think of many times when I've been working toward a goal, and become frustrated that I'm not there yet or haven't made as much progress as I think I "should" have. Ultimately, transformation should involve recognizing the small changes, and celebrating the mini milestones/achievements in our lives.
