I suspect I'm not the only one - after all, how often have we heard the "In my day, X was better because of Y!" That's really all about perception, though.
As far as this week's topic goes - we seem to be wavering on regrets and things that got away or are getting away from us.
Seems to me it's all fairly intertwined, but I haven't really seen anyone terribly unhappy with the way things have turned out. I mean, you can sit there and think about the past and play the "what if" game all day - and while it's fun in small doses, to focus on the past too much means you're not really living for the future. You can't change what happened - but you can change what will happen (at least as far as your own personal reactions and intentions are.)
But good or bad, these things shaped me into what I am today, so it's hard to be too regretful about that.
And really, it's all about taking these things and learning from them and always moving forward.
