Not exactly - but it is pretty good now.
I wish I hadn't spent my 20's lazing about and doing next to nothing, as I'm still paying for it now (just turned 40)
I wish I'd had the money to travel more, and I wish I'd had to foresight to take some risks, and make better judgements...
But, I've now got a pretty sustainable and reliable career (project management/Engineering/defence Industry) a fantastic Mrs and two brilliant kids.
We live in a nice area, but currently own the shabbiest house in our road, however, we are going to pull it apart and do a huge extension/renovation this summer which will provide a comfortable and safe palce for us all to live.
