Think for a moment about something that you cannot do. Something you have convinced yourself is beyond your capabilities and talents. Something just available to others.
For me one of those things was inversions, so head-down poses in yoga. But we each have many, some legitimately rooted in physical differences, but far too many rooted in beliefs about ourselves.
What do you tell yourself about you?
From early on in life we have learned to accept that there are things we can, and things we cannot do. We believe we are bad at math and good at languages. We believe some things are possible in life only for others.
