@Daojoan the "won't fix" is just the natural evolution of acceptance. In your example of being late, you accepted that you tend to be late and take responsibility to not inconvince other people.

Your idea of acceptance is of a wet wipe. An apathy to everything. An idea that you should stop caring about everything.

From my experience, acceptance is detachment from emotionally charged things; It's a capability to take any action regardless of emotional state.
