I'm with ya, there. If we don't review what we did in the past that went wrong, then what is to prevent us from repeating the same behaviour we are essentially "trained" to do?

Dwelling on it, without "mindfullness" is not good. DBT term. Gotta look at it without judgement is what DBT tells you...

Being in the now is a really strange concept. On one hand, it helps one to focus, but on the other hand, how does one plan a strategy that will ultimately affects the future if there is no review of the past?

This one I really have a hard time wrapping my head around.

Can't see where this is an upsetting question, though.
