What about "looking back?

[PPAULO]

Carlos, somehow "looking back" is 'to return' to the past and realize something, to learn something from it, review what came from it (for the better or for the worse) etc. Could be a "pensando bem" with focus on the "pensando".

In retrospect - may work both ways, with the focus on the "pensando" and "pensando bem" (making a contrast, contrasting, etc): Now, in retrospect, I shouldn't have done that.
(it was a bad idea to do that, so in retrospect could work both ways "olhando pro passado/" or "pensando bem").
