Two pairs of decisions in my past had amazing impact on my life.
Deciding to marry the 1st husband was one of the stupidest things I have ever done; the 2nd was waiting 6 months to divorce him instead of 6 days!
At least I learned an amazing amount about other people and myself very quickly, and it has served me very well over the years. Now I refer to it as my temporary fit of insanity.
The second pair was agreeing to move in with the man who was to be my 2nd husband. We had a really good 15 years.
When we decided to divorce it was the right time and a good decision for both of us in the long run.
Things might have been better had I chosen otherwise in 3 out of 4 of those decisions. My gut tells me all but the 1st one was the right move, but even that provided some very good lessons as quickly as possible.
