If you could go back in time and change one day what would it be?

There are some days I would erase. They caused me disgusting trouble.

I ****** something up real bad in the past. My loved ones warned me not to do it. But i didn't listen. And i regret it now. Wish i could go back and change it. But that's not gonna happen.

In my case, I would changed the day back in December of 1966 when my wife-to-be and I got carried away one night and she got pregnant. I definitely married the right woman, but it was a rough start for us, let me tell ya, especially since she was from a VERY traditional Sicilian family.

OK, so I wasn't a saint! But I am now.

The day when my mother was 3 months pregnant.

I would tell her to get an abortion.

Sorry.

I’ve had a wonderful enjoyable life, with a wonderful enjoyable wife.
But, like a wise man said, it’s all meaningless.

If you're referring to Solomon he didn't actually say "meaningless".
That is a poor translation.
The actual meaning of the word is vapor or breath, so the connotation is that life is brief and time here is like a morning mist, only there for a short time.
As such we should make the most of it, recognizing that our duty is to God not men.

The day I committed to financing a 90 acre
real estate development. (It went tits up.)

If you could go back in time and change one day what would it be?For me I am just fine. What about everyone else?

The day I called the community service board to make an appointment for depression. I don't know where'd I be in a good way if I went outside the county network to a private doctor for help. The whole experience was traumatic in addition to other stuff, but then I'm a bit scared of the butterfly effect-I'm safe and mind is free(er), what more can I ask?
