It was my duty to shoot the enemy and I don't regret it. My regrets are for the people I couldn't save: Marines soldiers buddies. I'm not naive and I don't romanticize war. The worst moments of my life have come as a SEAL. But I can stand before God with a clear conscience about doing my job.

I was the guy who was constantly speaking out against the Vietnam War. I have no regrets about that.

The truth is I'm proud of the life I've lived so far and though I've made my share of mistakes I have no regrets.

Make the most of your regrets never smother your sorrow but tend and cherish it till it comes to have a separate and integral interest. To regret deeply is to live afresh.

Of course there are regrets. I shall regret always that I found my own authentic voice in politics. I was too conservative too conventional. Too safe too often. Too defensive. Too reactive. Later too often on the back foot.

I'm torn about late parenting. I believe people should spend their twenties living and having fun and not having any regrets later. I also think people in their thirties generally make better parents but so many of my friends are having trouble - myself included - as fathers get older.

I haven't lived a perfect life. I have regrets. But that's from a lifetime of taking chances making decisions and trying not to be frozen. The only thing that I can do with my regrets is understand them.

I want to live my life so that my nights are not full of regrets.

You make mistakes but I don't have any regrets. I'm the kind of person who takes responsibility for it and deals with it. I learn from everything I do. I work very hard I have so many things going on in my life. Get to know me and see who I am.

Maybe all one can do is hope to end up with the right regrets.
