Wow… This so moving!
My answer would be Yes and No.
Yes — applies to only few situations where I knew what I am doing would lead to regret one day and not having any other choice.
No — If I hadn't done what I did, I wouldn't be where I am right now with so much of life lessons in my bag to guide my path to the future!
PS: Loved your tribute and wish you both more happiness and success in your endeavors :)
