Regret is insight that comes too late

Speaking from where I am at in life right now, it was so much better to be young, naive and less educated. Yet there were other things to complain about at the time, in other words one is never fully satisfied. Moreover I found a photo taken 4 years ago, 2004, which brought about feelings of nostalgia and I realise that there are so many mistakes that 'the girl on the photo' would never have done. Knowing that I made those mistakes and worst of all that making them undone is out of reach makes me wish I could start over which is why I try to hold on to a time when regrets were not present. I can not explain what happened and why, because I was naive and unaware. Although from the depths of my heart, I have owned my mistakes and take responsibility for my responses to all situations in my life but have no control over any of it, any more. Furthermore there are not to many left, who have not been overcome, piece by piece and sometimes, like now, it takes a nip at me but I'm too quick to ever be eaten by the monster of the past.
