I think all our lives are full of events, some of course we had no control over, but life goes on no matter.. The best thing to do is not dwell on the past and light up a big spliff sit back and think of what good we can do in the future..
I don't think wisdom would spoilt everything, we all make mistakes we would like to have not, and if the chance to do it over again would we go in that direction? I certainly would take the road less trodden.
Build it and they will come...
I hope something seasonal at least..
