Regrets

Today I want to quote the words of another famous song, Edith Piaf's "Je Ne Regrette Rien" (= I don't regret anything). She sings:
"No... je ne regrette rien. Ni le bien, ni le mal, tout ca m'est egal" (sorry, no suitable accents on my keyboard).
No, she says, I regret nothing, neither the good nor the bad. I don't mind any of it.

Strong words, aren't they?
How do you feel about your own past? Any guilt? Any resentment? Remorse? Gloom? Peaceful acceptance?
What about a little self-examination?
