Seems fairly evident to me that the definition of Self most citizens of developed nations are operating from is harmful.
At best, a marketing device. At worst, something more sinister.

Wounding your sphere of interests in tight knots around your body and mind is (literally) self-limiting and enervating.
A huge amount of "you" is socially and environmentally contingent, and contains most of your real drives and needs.

The wider, broader and deeper your sense of self, the more you can do, the more you escape depressive self-referentiality.
There is always something interesting going on. It isn't always located in your thoughts, nor in your body. Those places can be really dull.
