Oh I hear you! I should have gone to France on a year out from uni, but at the time I thought 5 years was too long for an Arts degree... it was nothing in your early 20s ffs!
If I had done that, I would never have met The Twat of my username. Though I also wouldn't have had my three amazing children, nor would I have met one of my oldest and dearest friends of 40 years.
I wish I had never taken sides in a power struggle between very senior managers that in the end, fucked up my career. My integrity remains intact, but it doesn't pay the bills.
That I didn't accept the job offer that would have avoided the above, with that job being almost immediately regraded after I turned it down, and wouldn't have involved a 64 mile daily commute. My mother put me totally off it by saying that it would be good if I had children, and I didn't want them at the time!
Getting a 2ii in my degree after 2xA and 2xB in my A levels (pre A*) - but it spurred me on to get a Distinction in my MSc.
That when the One Who Got Away when I was just 19 asked if I would be in the city over Christmas, I said no, because I had a Christmas job... then he met someone else and dumped me... but his wife is quite frumpy (he was always so trendy and cool!) and my kids are better looking than his so...😄
